Snails typically avoid sunlit areas, but some snails infected with certain parasites become attracted to light and prefer sunlit areas. Which of the following is the most likely hypothesis given the life cycles of many parasites?

A. The parasite itself must be exposed to light in order to survive in the snail.
B. The snail is behaving differently in order to rid itself of the parasite.
C. The parasite must exit the snail in a sunlit area in order to move and find its next host
D. The snail is dying from the parasite and is therefore looking for the light.
E. The parasite manipulates the behavior of the snail so that it gets eaten more readily, which allows the parasite to complete its life cycle.
