Solution

The correct option is B Centriole
The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus, when it is time for cell division. Mature neurons lack centrioles, which prevents them from dividing mitotically. Because they are difficult to replace, neurons are intended to last for a lifetime.
