Solution
The correct option is C Auxin
Auxin is a plant growth hormone used to promote initiation of adventitious roots and are the active ingredient of the commercial preparations used in horticulture to root stem cuttings. They can also be used to promote uniform flowering, to promote fruit set, and to prevent premature fruit drop. Typically, the end of a shoot contains an apical bud, which is the location where shoot growth occurs. The apical bud produces an auxin (IAA) that inhibits the growth of the lateral buds further down on the stem towards the axillary bud and promote the stem elongation.
