Solution

The correct option is B Ciliata
Ciliates are protozoans characterized by the presence of hair-like organelles called cilia that help in locomotion and feeding. All ciliates are uniquely characterized by the possession of two kinds of nuclei, a small micronucleus for sexual reproduction and a large macronucleus for all other processes.
Thus the correct answer is option B.
