B. Lappets	(ii) Flame cells
C. Cercaria	(iii) Sporocyst
D. Juvenile fluke	(iv) Miracidium
E. Second larval form	(v) Metacercariae

• A. A-(iv), B-(i), C-(ii), D-(v), E-(iii)
• B. A-(i), B-(ii), C-(iii), D-(iv), E-(v)
• C. A-(ii), B-(v), C-(iv), D-(i), E-(iii)
• D. A-(iv), B-(i), C-(iii), D-(ii), E-(v)

Answer 1

The correct option is A A-(iv), B-(i), C-(ii), D-(v), E-(iii)

A cercaria (meracidium, a larval form) has a tapering head with large penetration glands.
Redia larva contains two processes near the foot is called as lappets, which anchor in the tissue of the snail.
A flame cell is a specialized excretory cell in simplest freshwater invertebrates.
Metacercaria excyst in the small intestines releasing juvenile worms/flukes.
Sporocysts are the second larval stage in the life cycle of parasitic flukes.
So, the correct answer is option A.
