Correct Answer is D

Explanation

A. Over secretion of aldosterone: Aldosterone promotes water reabsorption, which reduces urine output.
B. Decreased GFR (glomerular filtration rate): This would lead to less urine formation, not polyuria.
C. Activation of angiotensinogen: This ultimately leads to water retention, not increased urination.
D. Deficiency of ADH: ADH (antidiuretic hormone) promotes water reabsorption. Its deficiency (as in diabetes insipidus) leads to excessive urine output.

A. Causes the release of ADH B. Blocks the reabsorption of Na+ C. Activates the renin-angiotensin-aldosterone system D. Decreases GFR (glomerular filtration rate)

Correct Answer is B

Explanation

A. Causes the release of ADH: ADH reduces urination by promoting water reabsorption.
B. Blocks the reabsorption of Na+: Most diuretics act by preventing sodium reabsorption, which in turn prevents water reabsorption, increasing urine output.
C. Activates the renin-angiotensin-aldosterone system: This system conserves fluid and reduces urination.
D. Decreases GFR: Decreasing GFR reduces urine production.
