Solution

The correct option is D Interphase
The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division. The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division.
During the S-phase of the interphase, the centrioles separate and undergo duplication which produces two pairs of centrioles.
