I think its D but don't be so hasty, wait for other answers because I might be wrong, I'm 16 and astronomy amateur, that's just my opinion so yeah...

The answer is actually D) a red giant.
The temperature of a star corresponds to it's color. Very hot stars appear blue, medium range temperatures cause yellow stars (like our own) and low temperature stars appear red. Our sun has a temperature of about 5,500 Kelvin. A red giant would be massive (as the question says "A very large star) and it would be thousands of degrees less (around 3,000 or so).

It's D - Red Giant.
Red Giants are stars that are in the stages of dying... our sun will go through this phase in a few billion years.
