D Correct answer
Explanation

At 28°F and 32°F, water is frozen or at its freezing point. The coin dropped into glass A (28°F) would land on ice since water freezes at 32°F. Similarly, glass B at 32°F would contain ice or water at freezing temperature. Coins would not sink through ice, so neither would reach the bottom.
