Answer to Question 1

c

Answer to Question 2

Osmotic thirst is caused by an increased concentration of solutes in the extracellular fluid, either by increased salt intake, or water loss. Osmotic thirst is detected by neurons in the OVLT that cause increased release of vasopressin (which decreases urine output and raises blood pressure) and increased activity in the LPO to initiate drinking, preferably of pure water.
