Answer: (D)

A- (III), B- (V), C- (I), D- (II)

Mehlis glands are present surrounding the ootype of Platyhelminthes and is a part of the female reproductive system of Platyhelminthes. Its secretion lubricates the passage of uterus through which ova moves.
The vitelline gland secretes substances for the development of the egg yolk and the formation of the shell/capsule around zygote.

The excretory system of fasciola is concerned with excretion as well as osmoregulation. It consists of flame cells.
The flukes and tapeworms possess an external covering known as tegument, formed of nonciliated extensions of large cells within the mesenchyme.

Thus, the correct answer is the option (D).
