Wrigglers refer to the larvae of mosquitoes. These are produced when the egg hatches and moves by wriggling. They live in water but breathe air, so like snorkelers, they have a breathing tube and must come close to the surface often to get oxygen.
The immature form of cockroach is nymph, larvae of the butterfly is called as a caterpillar, larvae of a housefly are maggot.
Therefore, the correct answer is option B.
