Here is an explanation:
The contractile vacuole in some unicellular organism is responsible for osmoregulation. (regulation of water and PH balance).
the contractile vacoule is the excretory organ of the unicellular organism,amoeba.so it retains water form its environment and excretes excess water from the organism
The answer is E. because the function of the contractile vacuole is to collect and pump water out of the cell through a process called osmoregulation.
The contractile vacuole of an amoeba is used mainly for excretion of waste products by diffusion
process by which amoeba excrete water water through it contractile vacuole is know as diffusion becos d area to volume ratio is high
The answer is c because contractile vacuole is an excretery organ for protozoa and amoeba is a protozoa
