A) \[IAA\]
B) \[G{{A}_{3}}\]
C) \[ABA\]
D) \[2,4-D\]
Correct Answer: D
Solution :
ABA (Abscisic Acid) inhibits synthesis of RNA and proteins. It has been shown that ABA regulates the expression of certain genes during seed maturation under certain stress condition such as heat shock, adaptation to low temperature and tolerance. IAA (Indole 3-Acetic Acid) is a natural auxin whereas 2, 4-D (2, 4-dichlorophenoxy acetic acid) is a synthetic auxin. \[G{{A}_{3}}\](Gibberellic Acid) is secreted from a parasitic fungus Fusarium moniliform (Gibberella fujikuroi).
