A
A-(iv), B-(iii), C-(v), D-(ii), E-(i)
💡 Explanation:
IAA is an auxin but has potential role of herbicide and weedicide. ABA is stress inducing plant growth regular. It can induce closure of stomata, Ethylene on other hand increases climactic rate and hence used for fruit ripening, GA or gibberlic acid are known to cause bolting in crucifers. Cytokinins were first isolated from Herring sperm DNA.
Thus, the correct answer is 'A-(iv), B-(iii), C-(v), D-(ii), E-(i).'
