Answer #1

(c) actomyosin

A spindle of great fibres starts to develop throughout prophase. It includes microtubules which can be made from protein called tubulin and sure other associated proteins. these sensitive fibres radiate from the centriole and constitute aster.

This feature was not given within the entrance paper. As actin and myosin are worried as contractile equipment in lots of nonmuscle cells so it may be taken into consideration as the appropriate answer. Myoglobin is present in muscular tissues that could bind to oxygen.
