In classical conditioning, a stimulus is used to provoke or elicit a response that a. it didn’t elicit naturally before conditioning occurred b. it elicited naturally before conditioning occurred c. was impossible to elicit before conditioning occurred d. was only elicited on occasion before conditioning occurred

A. it didn't elicit naturally before conditioning occurred

Explanation:

Classical conditioning consists in associating an initially neutral stimulus with a significant stimulus. Therefore, when the neutral stimulus is presented, in the absence of the other stimulus, a similar response will appear that would occur if the significant stimulus was presented. This ability to associate stimuli, however disparate, helps us in various daily situations. From this we can conclude that in classical conditioning, a stimulus is used to elicit or obtain a response that was not naturally elicited before conditioning occurred.
