Solution

The correct option is B Centriole
The spindle apparatus of a cell is comprised of spindle fibers, motor proteins, chromosomes, and, in some animal cells, microtubule arrays called asters. Spindle fibers are produced in the centrosome from cylindrical microtubules called centrioles.
Thus correct answer is A.
