Cartwheel structure is found in centrioles of microtubules in animal cell but centrioles are absent in plant cell therefore statement A is wrong.

A pair of centrioles are present in centrosome within a pericentriolar area without any membrane and they can duplicate themselves therefore both statements B and C are correct.

The microtubule contain tubulin protein instead of dynein and therefore statement D is also wrong. 

Hence the correct option is 2.
