Pleasant memories are most likely to be evoked by exposure to

A) bright colors.
B) soft touches.
C) fragrant odors.
D) loud sounds.

Fragrant odors have a strong association with memory and can evoke pleasant memories because the olfactory bulb is part of the brain's limbic system, which is involved in the processing of emotions and memory. Bright colors, soft touches, and loud sounds are not as strongly associated with memory recall.
