Answer:
Option A, conditioned stimulus , is the right answer.
Step-by-step explanation:
The conditioned stimulus is a component of the education theory of Classical Conditioning. In such a theory, a conditioned stimulus is a vague stimulus that triggers some kind of response when matched or amalgamated with an unconditioned stimulus. The response that occurs is then referred to as conditioned response.
In simple terms, it makes an organism respond to something as it is related to something else.
