Solution
The correct option is A IAA
Auxin is a group of several natural (and artificial) plant hormones; the most common and physiologically important auxin is indoleacetic acid (IAA). Some manufactured, or synthetic, auxins have structures similar to that of IAA. The synthetic auxin naphthalene acetic acid stimulates root development on stem cuttings and is used for asexual propagation, particularly of woody plants with horticultural importance.Thus, the correct answer is option A.
