Solution
The correct option is D Lymph vessels of man
Development of microfilariae occurs, if they are sucked by the mosquito species of Culex, Anopheles and Aedes which act as vectors. In the mosquito gut, the microfilariae lose their sheath and migrate to thoracic muscles and undergo two moultings (cast off old skin) there. It is the infective stage which requires two weeks time for development. Then, they migrate to the labium of mosquito when the infected mosquito bites a healthy person the microfilariae get under the skin and later migrate into the lymphatic system of man. There, they undergo third and fourth moult and develop into adult. In the host body, the adults live up to about 4 to 5 years.
