Solution

The correct option is A If both the assertion and the reason are true and the reason is a correct explanation of the assertion
The surface of centromere bears a special trilaminar plate called kinetochore. Kinetochore has points for attachment of microtubules. Microtubules produce chromosome fibres or tactile fibrils require for the movement of chromosomes during anaphase.
So, the correct answer is 'If both the assertion and the reason are true and the reason is a correct explanation of the assertion'
