Concept: This question tests your knowledge of modified root structures, specifically stilt roots, and their occurrence in common plants.

Why (C) is correct: Sugarcane (Saccharum officinarum) is a classic example of a plant that develops stilt roots. These are adventitious roots that grow obliquely from the lower nodes of the stem, providing extra mechanical support to the tall, slender stem, especially in windy conditions or when the plant is laden with sugar.

Why other options are wrong:

• (A) Groundnut: Groundnut (peanut) has a taproot system and modified adventitious roots called 'pegs' for fruit development, not stilt roots.
• (B) Rice: Rice has a fibrous root system.
• (D) Wheat: Wheat also has a fibrous root system.

NEET Tip / Mnemonic: Think of 'S' for Sugarcane and 'S' for Stilt roots. Also, remember that stilt roots are a type of adventitious root modification for support.

Correct Answer: (C)
