Solution
The correct option is C NAA
NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cutting. It is also used for plant tissue culture. The hormone NAA does not occur naturally, and, like all auxins, is toxic to plants at high concentrations. NAA is widely used in agricultural purposes. It is considered to be only slightly toxic but when at higher concentrations it can be toxic to animals.
