Solution

The correct option is C Fresh water Protozoa
In Freshwater Protozoa, are subjected to a hypotonic environment.
Water flows across their plasma membrane since their cytosol is always hypertonic to the environment.
Many wall-less protozoa have an organelle, the contractile vacuole complex (CVC), that collects and expels excess water.
Hence, Contractile vacuole is mostly present in Freshwater Protozoa.
So, the correct answer is 'Freshwater Protozoa'.
