The correct answer is:

Asexual reproduction is advantageous over sexual reproduction because it decreases the snails' need for social interaction.

Explanation:

Based on the given subject above about mud snails, wherein scientists watched the season in which they mated, the number of offspring they created, and the results of such stressors as drought, starvation, and lack of mates. Asexual reproduction gives the capability to produce large quantities of offspring. This helps to fill up the niche's quickly and prevent thieves and competition from invading. Finding a mate can be very difficult for people that are in desolate environments, like the deep ocean. And it also prevented the need of social interaction for snail.
