Answer:
d. a specific phobia
Explanation:
A specific phobia is a term used to refer to an irrational fear, a fear that has no reason to exist but is strong enough to prevent a person from doing certain activities. An example of this is Laverne's fear of cats, and no cat has triggered that fear, but Laverne is so terrified of the animal she avoids, including going to the house of friends who have cats.
