Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Compound umbel is branched and In compound umbel, both involucre and in volucels are present. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. An umbel is an inflorescence which consists of a number of short flower stalks which spread from a common point, somewhat like umbrella ribs. The arrangement can vary from being flat-topped to almost spherical. Umbels can be simple or compound. The secondary umbels of compound umbels are known as umbellules. A small umbel is called as an umbellule. The arrangement of the inflorescence in umbels is referred to as umbellate or occasionally subumbellate. In this inflorescence of flowering plants an involucral bract or a pair, whorl or other collection of such bracts, surrounding an inflorescence is present. Therefore, the correct answer is option B.
