D Correct answer
Explanation

Blue stick is the 1st stimulus, and then odor of cat is the 2nd stimulus, but then only blue stick generated fear in rat. In this experiment, 5 seconds after the introduction of blue stick,  the odor of cat was sprayed at one corner of the cage. Subsequently, the rat learns to associate stimulus 1 (blue stick) with stimulus 2 (cat body odor). It responds as soon as the blue stick appears and before the odor of the cat is sprayed.
