Answer 1

Answer:option (c)

Explanation: The natural name of Auxin is Indole Acetic Acid(IAA)

Answer 2

Answer:

The term ‘auxin’ is applied to the indole-3-acetic acid (IAA), and to other natural and synthetic compounds having certain growth regulating properties. All natural and synthetic auxins have been used extensively in agricultural and horticultural practices

Natural Auxins like IAA and indole butyric acid (IBA) have been isolated from plants.

NAA (naphthalene acetic acid) and 2, 4-D (2, 4dichlorophenoxyacetic acid) are synthetic auxins.

Hence IAA, IBA, NAAbelong to Auxin.

So, the correct answer is ' IAA, IBA, NAA'.
