Answer 1

• Mehlis gland also called Shell gland, is primarily present surrounding the ootype of Platyhelminthes, and it is a part of the female reproductive organ of Platyhelminthes. The passage of eggs in the uterus is lubricated by the secretion from Mehlis's glands.
  
• A flame cell is a specialized excretory cell found in the simplest freshwater invertebrates, including flatworms (except the turbellarian order Acoela), rotifers and nemerteans; these are the simplest animals to have a dedicated excretory system. Flame cells function like a kidney, removing waste materials.
  
• The flukes and tapeworms possess an external covering known as tegument, formed of nonciliated extensions of large cells within the mesenchyme. The tegument not only provides protection, but it is the site of exchange between the inner body and the outside environment; everything moves into or out of these worms across the tegument.
• The vitelline gland produces the vitelline globules, which some of them produce the egg-shell and some provide nutrient for the developing embryo within the egg.
  

So, the correct answer is 'A-3 B-5 C-1 D-2'.
