Question

Which hormone is used to increase the size of fruit?

• A. Auxin
• B. Gibberellin
• C. Cytokinin
• D. Ethylene

Hint:

Gibberellins are widely used in agriculture to improve fruit quality and yield.

Answer 1

The Correct Option is B

Gibberellins, plant hormones, facilitate cell elongation and division, thereby increasing fruit size. Applications comprise:

• Augmenting the dimensions of grapes and apples.
• Inducing seed germination and stem elongation.

Auxins and cytokinins also contribute to growth, but their role in fruit enlargement is less pronounced. --- Final Answer: \[ \boxed{\text{Gibberellin}} \]
