a. active
b. inactive
c. proactive
d. retroactive

D)

Explanation:

Retroactive interference is considering when some previous task or material is forgotten because of the new one.

In this case, Jason was studying Spanish and because of his switch to Pashto, he can only remember Pashto's vocabulary now. His new memories are dominating over the old ones.

One of the ways to stop this interference is to sleep better.
