B) Because it may crack due to high frequency.
C) Because it will prevent the food items to become hot.
D) Because of the danger of getting a shock from accumulated electric charges.
Correct Answer: D

Metals may also melt from heating. The porcelain container remains unaffected and cool, because its large molecules vibrate and rotate with much smaller frequencies and thus cannot absorb microwaves. Hence, they do not get heated up.
