Answer 1

Answer: (B)

Mostly in the dicotyledonous plant, radicle gives rise to primary roots, which gives lateral branches finally forming a taproot system. In monocot, primary roots are short-lived and form fibrous roots for support. Roots develop from other parts than radicle, and this type of root is called adventitious root.
