Boiling requires
a. the removal of energy.
b. the absorption of energy.
c. no energy change.

Boiling requires the absorption of energy.

Explanation:

Energy is the ability of bodies to affect a job because of its constitution (internal energy), its position (potential energy) or its movement (kinetic energy).

On the other hand, boiling is the physical phenomenon produced when the temperature of a liquid rises sufficiently to cause the set of molecules of the liquid to raise its vapor tension to reach the external pressure. Then gas bubbles appear throughout their mass and they are released into the atmosphere.

The temperature of matter is linked to the kinetic energy of its molecules (energy associated with movement). In order for the boiling of a liquid to take place, the temperature needs to be increased, that is, it is necessary to increase the kinetic energy of its molecules. That is, to reach the boil, the molecules must break their bonds, stronger in the liquid state than in the gaseous state. For that, energy is required. Therefore, boiling requires the absorption of energy.
