Question

cucumber carrot onion aur potato inmein se odd one kaun sa hai aur vajah bhi bataen ki yeh hai odd-one kyu hai​

Answer 1

Explanation:

Ginger is the odd one.

This explanation is based on the reproduction of the plants. Some of the vegetables grow from leaves, some grow from roots and some from stems. Now, all the other vegetables grow underground from roots but, fingers grow above the soil from the stem.

Basically, ginger is an underground stem. But, it is sometime mistaken as a root. Ginger grows from buds which in turn grows from tiny outlets on the under-grown stem. This takes the shape of a ginger.
