The correct answer for a ciliated protozoan is Paramecium. Here is a description and relevant hashtags for your MCQ post.
Ciliates are a group of single-celled protists (protozoans) characterized by the presence of numerous tiny hair-like organelles called cilia that cover their surface[wikipedia +2]. These cilia are used for locomotion, feeding, and sensing the environment[vedantu +2]. Paramecium is the best-known example of a ciliated protozoan and is commonly found in freshwater environments[doubtnut +1]. Ciliates have two types of nuclei (macronucleus and micronucleus) and reproduce both sexually and asexually. They play an important ecological role as part of the aquatic food web.
