Correct answer

B. IAA, Kinetin, Zn

Step-by-step solution

Plant growth regulators are small, simple molecules of diverse chemical composition, which in low concentration regulate growth, differentiation and development by promoting or inhibiting the same. Kinetin is a synthetic cytokinin and zinc ( Zn ) is not a natural plant growth regulator.
