Correct answer: D
Hormone action involves their reception by target cells. Specific proteins called hormone receptors that are located in target tissues only bind with these hormones.

Steroid hormones, bind with intracellular receptors while some hormones e.g., pituitary hormones like FSH bind with membrane bound receptors.
