Answer 1

The correct option is A A- (T),B- (R),C- (P),D- (Q)

Cytokinins produce Richmond Lang effect by delaying the process of ageing. It increases the productivity of the plant.

Auxins is a plant growth hormone which is mainly responsible for apical dominance.

Abscisic acid is mainly involved in the closure of stomata and reduce transpiration so it is known as the stress hormone.

Ethylene is responsible for ripening of fruits.

So, the correct answer is option A.
