It would 7 billion years which is B.

Answer: b) 7 billion years

Explanation:

Hi, the sun, like all stars, has a lifespan, characterized by a formation, main sequence, and eventual death

This lifespan began roughly 4.6 billion years ago, and will continue for about another 7 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

So, the Sun is about half way through the most stable part of its life.
