Explanation / Answer

C)

It changed the behavior of the pill bug so it did not hide anymore

Explanation :

Pill bugs live in moist forest soils, where they can hide from the birds that would eat them. If you take them out, they'll scurry back in. They're attracted to the soil by factors like humidity, dim light, and dark colors.

The healthy pill bugs behave this way . They stay in the humid chamber and avoid the dry one; they hide under the shelter and they choose dark gravel over light.

But the pill bugs that carries thorny-headed worms could be found wandering into the dry part of her chamber much more often than the healthy ones. A parasite would make its host crawl over the white gravel more often, and be far less likely to hide under the shelter. The parasitized pill bugs could no longer recognize these vital clues, and they became easier prey for birds.
