Crickets might be moving to new homes due to x reason but why will they move in the group? That is not answered by option B.

In the premise, we can see that survival is a huge risk for crickets bcos they are hunted down due to being alone,what would explain their sticking together inspite of them being solitary in nature?
I think between B and E, E explains why crickets migrate together(and hence stick together) to new homes. B only states that crickets are forced to LEAVE bcos of predators and turn in environmental conditions.. It doesn't mention why crickets would stay together .
E explains this phenomenon by saying that if crickets stick together, they are safer.
