Question

the stage that our sun is currently in. red giant supernova main sequence

Explanation:

The Sun is a medium - sized star. Stars spend about 90% of their lives in the main - sequence stage, where they fuse hydrogen into helium in their cores. The red - giant stage occurs when a star has exhausted most of the hydrogen in its core and expands. A supernova is a catastrophic explosion at the end of a massive star's life. Since the Sun is still fusing hydrogen in its core and has not yet exhausted its hydrogen fuel, it is not in the red - giant or supernova stages.

Answer:

C. main sequence
