Natural auxins and synthetic auxins are extensively used in
1 Agriculture
2 Horticulture
3 1 and 2
4 None of them
Explanation:
Auxins like IAA and indole butyric acid (IBA) have been isolated from plants. NAA (naphthalene acetic acid) and 2, 4-D (2, 4-dichlorophenoxyacetic) are synthetic auxins. All these auxins have been used extensively in agricultural and horticultural practices.
