• A. Entamoeba
• B. Amoeba
• C. Trypanosoma

Answer 1

The correct option is D Paramecium

Ciliated protozoans have a large number of hair-like organelles called cilia present all over the body surface that helps them in movement, feeding etc. They also have a mouth pore that opens to the outside, called the gullet into which they move their food by means of cilia. Paramecium belongs to this group of protozoans.

So, the correct answer is 'Paramecium'.
