Answer 1

The Correct Option is B

Gibberellins (GA) are plant hormones used to promote the elongation and enlargement of fruits, including grapes. Key roles of gibberellins in grapes include:
Stimulating cell elongation, leading to larger and more uniform grape size.
Reducing cluster compactness, making grape clusters more marketable.
Enhancing the overall quality of grapes by improving fruit development.
Farmers often apply gibberellins during fruit development to ensure better yield and quality.
Final Answer: \[ \boxed{\text{Gibberellin}} \]
