(i) Osmoregulation

(ii) Digestion

(iii) Reproduction

(iv) Excretion

(v) Bioluminescence

• A. (ii) only is correct
• B. (i) and (iv) are correct
• C. (iii) only is correct
• D. (i) and (v) only are correct
• E. (iv) and (v) are correct

Answer 1

The correct option is B (i) and (iv) are correct

Bundles of flame cells are called protonephridia. The function of these cells is to regulate the osmotic pressure and maintains ionic balance.
