Which characteristic is used to categorize the different kinds of animal-like protists?
a. type of reproduction
b. method of movement
c. method of digesting food
d. number of cells

The correct answer is option B

The protists are classified based on the method of movement. They have different kinds of locomotory organs that helps them to move from one place to another. Some protists have flagella,which is a propeller like structure that helps the protists to move.

Some of them have temporary feet called as pseudopodia. The cell extends itself and behaves as false feet and helps in the movement of the protists.

Some of the protists have cilia as their locomotory organ.

Thus, different locomotory organs shows that the protists are differentiated based on their movement.
