The correct answer is option 1: Ice melts more easily under black wrap.

When sunlight or heat energy is absorbed by an object, it causes the temperature of that object to increase. When the black wrap is used to cover the ice, the black color absorbs more heat energy from the surrounding environment compared to the white color. This means that more heat is transferred to the ice when it is covered with the black wrap, causing the ice to melt at a faster rate.

On the other hand, when the white wrap is used to cover the ice, the white color reflects more sunlight and heat energy. This means that less heat is transferred to the ice, resulting in a slower melting rate compared to when the ice is covered with the black wrap.

Therefore, option 1 is correct because the ice will melt more easily under the black wrap. The white wrap will slow down the melting process by reflecting heat energy away from the ice.
