If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Solution
Assertion:
Gibberellic acid increases the length of grape stalks. Gibberellins are plant growth regulators that increase the length of the axis, which promotes stalk elongation. This property is used commercially for plantation purposes.
Reason:
Ethephon hastens fruit ripening in tomatoes and apples. Ethephon is a plant growth regulator that promotes fruit ripening, abscission, flower induction, and other responses. It is a widely used compound as a source of ethylene. In aqueous solution, ethophon slowly releases ethylene and is transported to various parts.
