Question

after a low - mass star (i.e., a star less than about 8 solar masses) exhausts the supply of helium in its core, it can fuse carbon into oxygen, neon, and magnesium. heats up and becomes a blue giant. explodes in a core - collapse supernova. will continue to fuse heavier elements, up until silicon fuses into iron.

Explanation:

Low - mass stars (less than about 8 solar masses) do not have enough mass and pressure to fuse carbon into oxygen, neon, and magnesium or continue fusing heavier elements up to iron. They also do not explode in a core - collapse supernova or become blue giants. After exhausting helium in their core, they enter the red - giant phase and eventually shed their outer layers to form planetary nebulae and leave behind white dwarfs.

Answer:

None of the above options are correct.
