Answer 2

Answer:

a(iv) , b(i) , c (iii), D (ii)

Explanation:

Weedicide is a term used for a chemical weed killer which is 2,4-D (2,4-Dichlorophenoxyacetic acid) and it is used to destroy broad leaf

Bolting is the premature growth of the flower stalk which produces seeds, also called running to seed, and this is induced by GA3 (Gibberellic acid).

Ethylene is a plant hormone which causes thinning of cotton, but the main function of ethylene is fruit ripening.

Lateral shoot growth is promoted by cytokinin.
