Answer 1

Animals may be defined as a member of the kingdom Animalia, which are generally characterized by a multicellular, having specialized sense organs, show voluntary movement, responses to factors in the environment and ability to acquire and digest food.
Examples of animals are horses, lions, leopards, marine turtles and Jaguar.

Complete answer:
In order to solve this question we need to know about the type of animals let’s learn about the solitary and sedentary animals.
- Solitary means in biology is living alone or in pairs, especially in contrast to related social forms.

- Sedentary means in biology is inhabiting the same locality throughout life; not migratory or nomadic.

- Sedentary animals include many protozoan’s, for example, some foraminifers, heliozoans, and infusorians (including vorticella and stentor).
Also sedentary are scyphozoans, sponges, hydroids, and coral polyp
Many of them live in the tubes of polychaetous worms.
For example: Barnacles, some bivalve mollusks, all bryozoans, brachiopods, stalked crinoids, and ascidians.

- Solitary animals: Solitary animal, an animal that does not live with others in its species.
For example: Marine Turtles, Snow leopard, Jaguars, etc.
Solitary animals move slowly whereas sedentary animals live on their own.

So, the correct answer is option C, Solitary animals move slowly; sedentary animals live on their own.

Note: A barnacle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustaceans.
Hence they are related to crabs and lobsters.
Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings.
