Model Answer

Option A — Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

Explanation

The textbook states that plants raised by vegetative propagation bear flowers and fruits earlier than those from seeds. The reason is correct: vegetatively propagated plants are genetically identical to the parent and bypass the juvenile/seedling phase, directly continuing from a mature parent's stage. Hence R correctly explains A.
