Correct option is C)

(i)Taproot - (b)Turnip

     A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downwards. For example, Turnip, beetroot, carrot, etc.

(ii)Adventitious root - (a)Sweet potato

     The roots arise from parts of the plant other than the radicle and are called adventitious roots. For example, sweet potato.

(iii)Stem  -   (d)Potato

     Stem tuber is a swollen tip of an underground lateral Stem (Stolon). It is covered by a corry Skin with a number of small depressions called eyes’. Each eye represents a node, bearing one or more buds subtended by a leaf scar (= scale leaf). A big scar at one end (heel end) of a potato marks its attachment to the stolen. Adventitious roots are usually absent. For example, Potato.

(iv)Fibrous root - (c)Wheat

     A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem. For example, Grass, wheat, rice, marigold, white clover, maize, banana, millet, bamboo, and onion.

So, the correct answer is 'b'(i) - b, (ii) - a, (iii) - d, (iv) c''.
