Answer 1

Answer: (A)

Tap roots

Fusiform, napiform, conical roots are the modifications of tap roots. In a plant with a taproot system, the taproot is the central and dominant root. Typically, a taproot is straight and very thick. It is tapering in shape and grows directly downward. Fusiform root is widest in the middle and tapers towards the top and the bottom. Napiform type of storage root has a top-like appearance. It is very broad at the top and tapers suddenly like a tail at the bottom. Conical type of root tuber is conical in shape, meaning widest at the top and tapering steadily towards the bottom.

Thus, the correct answer is option A.
