Solution

The correct option is B Calcium
Calcium is essential during cell division for the formation of mitotic spindle apparatus. The mitotic spindle is composed of spindle fibres. The spindle fibres attach to the kinetochore of chromosomes and help in chromosome movement. Spindle fibres are composed of microtubules.
The concentration of calcium increases during the mitotic phase and contributes to the stability of microtubules.
