Q. Potato and sweet potato :

(b) Have edible parts which are analogous organs
(c) Have been introduced in India from the same place
(d) Are two species of the same genus
Solution :
Correct option : B Potato and sweet potato are examples of analogous organs. Both sweet potato and potato have a common function i.e., storage of food in the form of starch.

Thus, option B is correct, potato and sweet potato are not homologous organs, have not been introduced to India and are not two species of same genus.
