Answer 1

The correct option is (d) Turn into a blue giant

Easiest explanation: If the star is much bigger than our Sun, about 10 times as massive, it will likely turn into a blue giant and be able to support fusion reactions in shells in its core when the helium builds up with enough heat and pressure to start fusing the helium into heavier and heavier elements.
