How does a high-mass star differ from a low-mass star as both enter the final stages of their life cycle?

A. A high-mass star dies more explosively.

B. A high-mass star ends in a nova event.

C. A high-mass star ends when it runs out of hydrogen.

D. A high-mass star converts helium to carbon, whereas a low-mass star does not.,

B. A high-mass star ends in a nova event. When a high mass star gets to the end of its life, the gravity of its mass collapses upon itself, causing the collapse to accelerate and cause a nova event. On the other hand, smaller mass stars typically either become white dwarfs or red giants, depending on the particular circumstances and mass of the star.
