Question

Assertion : Gibberellins cause fruits like apple to elongate and improve its shape.
Reason : $GA_3$ is used to speed up the malting process in brewing industry.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (B)

Application of gibberellins increases the number and size of several fruits e.g., grape, tomato. Size and shape of apple fruits is enhanced by application of $GA_4$, and $GA_7$ mixture. Gibberellins (e.g., $GA_3$) increase the yield of malt from barley grains i.e., malting.
