I. Coelozoic parasite
II. Histozoic parasite
III. Monogenetic parasite
IV. Digenetic parasite
V. Monomorphic, acoelomate parasite
VI. Dimorphic, pseudocoelomate parasite

• A. II, III, V
• B. II, III, VI
• C. II, IV, VI
• D. I, III, VI

Answer 1

The correct option is C II, IV, VI

• Statements II, IV, VI are correct. Wuchereria bancrofti commonly called filarial worm is a digenetic, dimorphic, pseudocoelomate, histozoic and pathogenic parasite.
• It is digenetic because it has two stages of multiplication in two different hosts, one sexual in the mature form, the other asexual in larval stages.
• It is a histozoic parasite as it lives in the tissue outside of a cell body.
  Hence, the correct answer is C.
