Solution
The correct option is B NAA
Auxin is a plant hormone which prevents the abscission of leaves and fruits. NAA is a type of auxin. Young leaves and fruits produce NAA and thus remain attached to the stem. When the level of auxin declines in fruits as compared to stem, fruit drop occurs. Hence, auxin is sprayed externally to prevent loss of fruit from premature fall.Thus, the correct answer is 'NAA'.
