Mango : Fruit :: Potato : ?

Answer: Option A

The analogy "Mango : Fruit" indicates that a mango is a type of fruit. To maintain the same relationship, we need to identify what a potato is classified as. The correct relationship should be "Potato : Root," as a potato is a type of root vegetable.

Option B: Stem – This is incorrect because a potato is not a stem. Potatoes grow underground and are classified as tubers, which are part of the root system.

Option C: Flower – This is incorrect because a potato does not refer to a flower. Flowers are the reproductive parts of plants, whereas a potato is an edible part of the plant that grows underground.

Option D: Fruit – This is incorrect because a potato is not classified as a fruit. A fruit is typically the part of the plant that develops from the flower and contains seeds, while a potato is a storage organ that grows from the roots.

Therefore, the correct answer is "Root", as it correctly matches the relationship in the analogy.
