Answer:
b. classical conditioning
Step-by-step explanation:
In psychology, the term classical conditioning refers to a form of learning in which an stimulus that triggers a natural answer by itself (unconditioned stimulus and unconditioned response) is paired with another stimulus that originally doesn't trigger any answer (neutral stimulus) but, after some repetitions, the answer evoked by the first stimulus starts to show up by presenting the originally neutral stimulus. Then, this answer is known as the conditioned response and the neutral stimulus has become a conditioned stimulus)
Therefore, in other words we can say that the type of learning in which a stimulus (conditioned stimulus) acquires the capacity to evoke a response (conditioned response) that was originally evoked by another stimulus (unconditioned stimulus) is known as B.classical conditioning.
