Potato : Carrot : Radish
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Groundnut
Potato, carrot and radish have one thing in common: the part we eat grows under the ground. The potato is a tuber, a swollen tip of an underground shoot, and the carrot and radish are swollen roots.
Option (1) Spinach — its edible part is the leaves, above the ground.
Option (2) Sesame — its seeds form in pods on the plant, above the ground.
Option (3) Tomato — a fruit that grows on the plant above the ground.
Option (4) Groundnut — after flowering, its stalks bend down and push into the soil, so the pods develop under the ground, like the edible parts of potato, carrot and radish.
