(a) tubulin
Explanation:
Spindle fibres of mitotic cells are made up of microtubules. It consists of protein tubulin that maintain cell shape, serve a tracks for organelle movement & help in cell division by getting attached to the centromeres of bivalents. They are arranged on equator due to congression movements. The movement of bivalents or chromosomes occur towards the poles as a result of spindle fibres contraction.
