Answer:

B. Energy was transferred

Explanation:

All chemical and biochemical reactions release or absorb energy from the environment in some way. Every process of heat transfer between bodies, substances and the enviroment is also considered a process of energy transfer.

The processes that release heat are called exothermic and give us a feeling of warmth. This is the case, for example, with combustion.

On the other hand, the sensation of cold we feel when leaving a bath, or when we take an ice cube, is associated with endothermic processes. Such processes, like evaporation and fusion of water, for example, absorb heat from the environment and this can also be perceived by our body.
