A Correct answer
Explanation

In Amoeba, osmoregulation (water balance) is performed by the contractile vacuole, which collects excess water and expels it from the cell. Ectoplasm is the outer gel layer, pseudopodia are for locomotion, hyaloplasm is the inner fluid, and food vacuoles digest nutrients.
