Correct Answer is D
Explanation
a) TRH → production of T3 and T4 → TSH: Incorrect order; TSH stimulates T3/T4 production, not the other way around.
b) TSH → production of T3 and T4 → TRH: Incorrect; this reverses the hypothalamic-pituitary-thyroid (HPT) axis.
c) TSH → TRH → production of T3 and T4: Incorrect sequence; the hypothalamus releases TRH before the pituitary releases TSH.
d) thyrotropin-releasing hormone (TRH) → thyroid-stimulating hormone (TSH) → production of T3 and T4: This reflects the HPT axis: TRH is released by the hypothalamus (first tier). TSH is secreted by the anterior pituitary (second tier). T3 and T4 are produced by the thyroid gland (third tier)
