increased levels of angiotensin II will cause an increased level of aldosterone which produces sodium and river reabsorption, increasing blood volume increasing blood pressure. (so you can exclude answers a, d and e)

Antidiuretic hormone will block aquaporines which are proteins that let your kidneys throw out water so it restricts diuresis (that's why it is named antidiuretic hormone) increasing blood volume and so on... (answer B excluded)

In the other foot, Atrial natriuretic peptide enhances the sodium excresion by your kidneys, sodium is always excreted with sea reducing your blood volume and therefore blood pressure.
