She asked him because if Draco was still alive, she had something to fight for. She had a reason to lie to Voldemort. If Draco is alive, she needs to get into the school to see him and protect him, and helping Harry feign death was the easiest way to do that. But if Draco was already dead, she wouldn't have bothered.
When Voldemort asked her to check if Harry was dead and she realised he was, in fact, still breathing, Narcissa seized her opportunity. Harry revealed that Draco was still very much alive, and she lied to her master in order to get closer to him.
She wanted to see Draco before anyone could kill him for his affiliation with the Dark Lord. Whether or not Harry was alive the answer was always going to be the same so that she could quickly see Draco.
Draco's refusal to reveal Harry's identity to Bellatrix was not because he liked him. It was because he believed that Harry was the only chance they had at defeating Voldemort. At first, Draco admired and revered Voldemort until he threatened his family's safety.
Harry tried to use this spell himself. The first time was against Bellatrix after she had killed Sirius. His attempt was unsuccessful because, as Bellatrix mockingly explained: 'You need to really want to cause pain – to enjoy it – righteous anger won't hurt me for long…'
She was remorseless and was cackling in glee after she had murdered Sirius. Bellatrix couldn't stop raving about it and showed it by singing “I killed Sirius Black” multiple times.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
Voldemort was scared it had gone wrong and was nervous to check. It was only when Narcissa checked that his arrogance returned. Only then he made up lies about Harry running despite all DE and Hagrid knowing that wasn't true.
In fact, Lucius' own support to Voldemort is revealed to come only under some form of duress, which is likely Narcissa's Veela Allure. When Lucius turns on Voldemort due to the reveal of his Horcruxes, Narcissa divorces him, taking 75% of Malfoy's wealth with her.
She managed to leave without confrontation by simply not returning home to the manor again, instead going to live with her sister and their friends when not at Hogwarts.
Narcissa was taught the philosophy of blood purity from a young age and grew up prejudiced in favor of pure-bloods. Thus, like her sister Bellatrix, she cut off contact with her sister Andromeda after she was disowned and burned off the Black family tree for marrying Muggle-born wizard Ted Tonks.
Though Narcissa may not necessarily have agreed with all of bellatrix's life decisions, and her views, she certainly loved her sister, and will have certainly mourned her death.
Draco Malfoy's mother Narcissa was cold, cunning and devoted to the Dark Lord. But she was also a mother, which meant she was willing to risk everything to make sure her son was safe.

Neville's role in the prophecy in Order of the Phoenix is frequently referred to in a hypothetical scenario where Neville was the Chosen One rather than Harry. It is often suggested that Voldemort chose Harry over Neville because of Harry's half-blood status.
A centaur named Firenze rescues Harry and carries him back to Hagrid.
The answer is that Sirius wanted to deflect attention from the real Secret-Keeper. He probably hoped Voldemort would go after him so he could steer attention away from Pettigrew.
"Why didn't you tell her? Bellatrix?" asked Harry, "You knew it was me. You didn't say anything. " Because Draco knew Bellatrix would called the dark lord, and dark lord would killed Harry Potter and his friends, and Draco is not as bad as his family.
After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse. It was a testament to Hermione's toughness that she was able to walk away without lasting damage.
