Answer:
C. Extinction.
Step-by-step explanation:
In psychological terms, extinction can be explained as how we can learn something new about a situation. It is not the same as forgetting though, and that is why you will learn that the animal can reverse to the undesired behavior sometimes.
Extinction becomes a learning process, as its neural substrates are now beginning to be understood. Though it is sometimes hard to distinguish classical conditioning from other forms of associative learning.
