Solution
The correct option is D Zinc
Zinc is a microelement that is used in the formation of IAA (indole acetic acid). IAA is a type of auxin which is one of the plant growth regulators generally found at the apices of the plant.
The plant growth regulators are small, simple chemical compounds that control the growth and development of the plants. Plant growth regulators are also termed as plant hormones or phytohormones. Phytohormones are composed of different chemical compounds like indole compounds, terpenes, carotenoids, gases, etc. These phytohormones are involved in both growth promoting as well as growth inhibiting activities.
