Which effect does the sun's energy have on a commet? A. It causes the comet to turn toward earth. B. It causes the comet to from a bright light. C. It causes the comet to break apart. D. It causes the core of the comet to melt.

I believe the answer is D. It causes the core of the comet to melt

Explanation:

C is wrong because the comet doesn't fall apart when in contact with heat

D is most accurate because imagine its a microwave it warms from the inside out, so The inside, core, of the comet would be subject to melting instead of falling apart, mainly because the outside and core are different

Hope this helped, and I apologize if this is wrong or if the explanation is confusing/incorrect.
