C. The iceberg has a lower temperature than the water.
D. Their temperatures are not the same but you can't tell which is greater without a thermometer.

Answer 1

The answer is D statement "Their temperatures are not the same but you can't tell which is greater without a thermometer". The iceberg can move through the ocean and passed through a various temperature of the ocean. The ocean stays at the same temperature whether it's lower or higher than the iceberg's temperature because of the salt.
