Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In racemose head, the main axis or receptacle is suppressed, becoming almost flat It bears a mass of small sessile flowers (florets) on its surface, with one or more whorls of bracts at the base forming an involute. The florets are arranged in a centripetal fashion, i.e, younger towards the centre and older towards the periphery The advantages of this kind of inflorescence are
that the head as a whole becomes more showy and attractive and the florets being close together one or a few insects can pollinate most of them within a short time.
So the correct option is B.
