Solution

The correct option is B If both assertion and reason are true but reason is not the correct explanation of assertion.

Plant growth regulators (PGRs) are small, simple molecules of diverse chemical composition, which in low concentration regulate growth, differentiation, and development by promoting or inhibiting the same. One type of plant growth regulators is plant hormones or phytohormones. Auxins are the phytohormones. They do not induce flowering in gymnosperms.
