Correct Option
The correct option is
Chilli : Fruit
Explanation
The plant morphology, specifically the classification of the edible parts of common crop plants. Botanically, edible parts are categorized as roots, stems, leaves, flowers, fruits, or seeds based on their origin and development.
Statement-wise Analysis
- (a) Wheat : Fruit – Contextually Incorrect
Botanically, a wheat grain is a caryopsis, a type of dry fruit where the fruit wall (pericarp) is completely fused with the seed coat. However, in the context of general classification questions, wheat is primarily categorized as a grain or seed (since the endosperm is the main edible portion), distinguishing it from fleshy fruits. While technically a fruit, it is not the "best match" when a clear fleshy fruit option is available. - (b) Potato : Seed – Incorrect
The potato is a tuber, which is a modified underground stem. It stores food and possesses "eyes" (nodes) capable of vegetative propagation. It is not a seed. - (c) Mustard : Root – Incorrect
The edible parts of the mustard plant are the seeds (used for oil and spices) and the leaves (used as a vegetable/greens). The root is not the edible part. - (d) Chilli : Fruit – Correct
Chilli is botanically a fruit (specifically a berry) that develops from the ovary of the flower after fertilization. The entire structure, including the pericarp and seeds, is edible. This is the most unambiguous and correctly matched pair.
Key Takeaway
Potato is a modified stem (tuber), Mustard is consumed for its seeds and leaves, and Chilli is a fruit. Wheat is botanically a dry fruit (caryopsis) but is conventionally treated as a grain/seed in contrast to fleshy fruits.
