• A. Auxins
• B. Cytokinins
• C. Gibberellins
• D. Ethylene

Hint:

Gibberellins are essential in promoting cell elongation and are commonly used in agriculture to increase the size and quality of fruits.

Answer 1

The Correct Option is C

Step 1: Gibberellins are plant hormones that play a critical role in promoting growth, including fruit elongation. They are commonly used to increase the size of fruits like grapes.

Step 2: - (A) Auxins promote cell elongation but are primarily involved in root growth and development.
- (B) Cytokinins are involved in cell division and promote shoot formation.
- (D) Ethylene is associated with fruit ripening rather than elongation.
Conclusion: Gibberellins are the hormone responsible for fruit elongation in grapes.
