Answer Key / Explanation : (a) -

(a)

Ethylene is a gaseous hormone responsible for fruit ripening. Germination of seed is triggered by soaking of seeds in water. After imbibing water, the embryo secretes gibberellin which stimulates the synthesis of  amylase. Gibberellin is not responsible for falling of leaves. Apical dominance of plants occur due to auxin hormone
