Hello there!
I would actually say that the answer would be "metal", but metal is NOT one of your options. But on thing that we would want to do is to find an element that would be very similar to metal, and also have the same affect of being hot or having heat trapped.
Ceramic shouldn't be the answer as ceramic is not a part of metal.
I would conclude that your answer should be "aluminum". The reason to why I would say this is because aluminum is the only substance that would seem to be the closest the the element metal, so this would be why I would say "a" is your answer.
A. Aluminum
B. Iron
C. Ceramic
D. Zinc
I hope this helps you!
