Cilia are a. similar to the bacterial flagella in that they rotate to allow motion. b. are temporary extension of the cytoplasm, used only for movement when resources are low. c. composed of microtubules arranged in a 9+2 (9 surrounding, 2 central) manner. d. composed of microfilaments arranged in a 9+2 (9 surrounding, 2 central) manner.

Explanation:

In many organisms, the function of cilia is same to flagella. It helps in the movement of organisms from one place to another in search of food and some other reasons.

Cilia is madeup of microtubules which are arranged in 9+2 form. 9 pairs of microtubules are present in fused form outside the cylinder while 2 microtubules are present in the center in unfused form.
