Answer:
The answer is probably D.
Explanation:
It's clearly not A and B. So, It all "boils" down to option C and D. Black surface absorbs the most heat, but also gives it out easily (Kirchoff's law of radiation). Now a metal cup with a glossy surface is going or reflect some of the light that strikes it. But a matte black surface helps it absorb the heat even though it can emit that heat fast.
