• A. A - 1, B - 4, C - 2, D - 3
• B. A - 2, B - 3, C - 1, D - 4
• C. A - 4, B - 1, C - 3, D - 2
• D. A - 3, B - 2, C - 1, D - 4

Answer 1

The correct option is A A - 1, B - 4, C - 2, D - 3

1.The conical fleshy tap root resembles a cone, that is, the thickest towards base and gradually tapering towards the apex, e.g., Carrot (Daucus carota) 2.The fusiform fleshy root is like a spindle, that is, thickest roughly in the middle and narrow towards both its base and apex, e.g., Radish (Raphanus sativus). 3.The napiform fleshy root is very thick at the base and is almost spherical. It suddenly thins out towards the apex (top-like), e.g., Turnip (Brassica rapa ) 4.The tuberous roots are those thickened tap roots which do not assume any definite form, e.g., Mirabilis jalapa (Four O’ Clock). So, the correct option is A. (A - 1, B - 4, C - 2, D - 3)
