$\left(b\right)$ ${GA}_3$	$\left(ii\right)$ Thinning in cotton
$\left(c\right)$ Ethephon	$\left(iii\right)$ Stress tolerance
$\left(d\right)$ ABA	$\left(iv\right)$ Brewing industry
	$\left(v\right)$ Weed free lawns

• A. $a-ii,b-i,c-v,d-iii$
• B. $a-v,b-iv,c-ii,d-iii$
• C. $a-v,b-iv,c-i,d-ii$
• D. $a-iii,b-ii,c-i,d-iv$

Answer 1

Answer: (B)

$a-v,b-iv,c-ii,d-iii$

A 2 ,4-D is a synthetic auxin. It is a weedicide. It kills weeds from the lawns. GA${}_3$ is a plant hormone which is used in brewing industry to hastens the malting process. Thinning is process in which increased rate of abscission of fruit is seen. Thinning in cotton is brought by applying ethephon, a commercial preparation of ethylene. ABA (abscisic acid) is a plant hormone. It is also called as stress hormone as it brings stress tolerance. During stress condition, its concentration increases.

Thus, the correct answer is B.
