Solution
The correct option is D Bougainvillea
Auxins are generally produced by the growing apices of the stems and roots, from where they migrate to the regions of their action. 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.They help to initiate rooting in stem cuttings, an application widely used for plant propagation in plants like Bougainvillea and Rose which are propagated vegetatively through stem cutting.
