Solution

The correct option is D Both Assertion and Reason are incorrect
Asparagus is a herbaceous, perennial plant with stout stems and much-branched, feathery foliage. Asparagus cannot be propagated vegetatively by the stem. It can be propagated by seed or through root division only.
Asparagus has stout stems with needle-like cladodes as 'leaves' (stem modification) over the ground. These stems do not possess circular nodes that have buds for growth of daughter plants as stated by the reason in the question. Asparagus plants do not propagate through leaves.
So the correct option is D.
