Answer 1

The Correct Option is C

The question requires identifying an example of an edible underground stem from the given options. To do this, let's analyze each option:

1. Groundnut: Groundnuts, also known as peanuts, are seeds, not stems. They belong to the leguminous family and grow as pods underground, but they are not stems.
2. Sweet Potato: Sweet potatoes are modified roots, specifically tuberous roots. They store nutrients and aid the plant with food storage, but they are not stem structures.
3. Potato: Potatoes are tubers, which are a form of an underground stem. Tubers are specialized structures that store starch and have nodes for budding. Potatoes have "eyes," which are nodes capable of sprouting new plants, confirming their identity as a stem.
4. Carrot: Carrots are a type of root vegetable known as taproots. They are not stems; they grow as part of the root system.

In conclusion, the edible underground stem among the options given is Potato. It is a tuber, a category of modified stems used for storage and propagation.
