Solution

The correct option is A IAA
Auxin is a plant hormone. IAA is a type of auxin present in the plant. It promotes growth in plants. It stimulates cell elongation. It is commonly used in stem cutting. In tea plantation, cutting is done which is followed by vegetative propagation. The cutting produces new roots and stems. The new plant thus produced is independent of the parent.
Thus, the correct answer is option C.
