Correct Answer :
B. cilia and flagella
Basal body is a short cylindrical array of microtubules. It is formed from a centriole andassociated with the formation of cilia and flagella. It is located at the base of eukaryotic cilia and flagella, which is a continuation of the 9 outer-axonemal microtubule doublets, but with the addition of a C tubule to form a centriole-like triplet. Basal bodies may be selfreplicating and serve as a nucleating centre for axonemal assembly, which are anchored in the cytoplasm by rootlets.
