- Correct answerD$\mathrm{A}=\mathrm{S} \quad \mathrm{B}=\mathrm{P} \quad \mathrm{C}=\mathrm{Q} \quad \mathrm{D}=\mathrm{R}$
Solution
Adrenal cortex produces steroid hormones like cortisol and aldosterone. Malfunction or hyposecretion of the adrenal cortex leads to Addison's disease. Thus, A matches with S.
Epinephrine is a catecholamine hormone secreted by the adrenal medulla that mediates rapid responses to external stimuli, often referred to as the fight-or-flight response. Thus, B matches with P.
Estrogen is a primary female sex hormone and is classified as a steroid hormone. Thus, C matches with Q.
Thyroxine is an iodinated derivative of the amino acid tyrosine, produced by the thyroid gland. Thus, D matches with R.
Combining these, we get A=S, B=P, C=Q, D=R.
Answer: $\mathrm{A}=\mathrm{S} \quad \mathrm{B}=\mathrm{P} \quad \mathrm{C}=\mathrm{Q} \quad \mathrm{D}=\mathrm{R}$
