Answer 1

The correct option is A a-(iii), b-(v), c-(i), d-(ii), e-(vi)

Vermicomposting is the use of earthworms as a composting method to produce vermicompost.

Pharyngeal nephridia discharge their wastes into the alimentary canal and are, therefore, enteronephric.

Integumentary nephridia are exonephric nephridia. Exonephric nephridia are those nephridia which throw their collected excretory matter directly outside the body wall.

Malpighian tubules are the excretory organs present in cockroach.

Amplexus: It is a type of fertilization which is seen in frogs that allows the male frog to place his cloaca near the females in order to fertilize her eggs.
