Thirst is activated bya) Increased Angitension II levelb) Extracellular hyperosmolarityc) Increaed ANP levelsd)  Increased Renin levels: (A) acd, (B) bcd, (C) abd, (D) ab
Answer is C. When plasma osmolarity increases, the Osmoreceptors are activated which results in increased thirst. Similarly, when hypovolemia occurs, Renin-Angiotensin mechanism gets activated which causes increase in Angiotensin II that stimulates the satiety centre.
