Select the correct option for the regulation of kidney function.

• A
  Excess of water in body $\rightarrow$ Osmoreceptors $\rightarrow$ Neurohypophysis $\rightarrow$ $ADH$ $\rightarrow$ Water secretion in distal parts of tubules $\rightarrow$ Decrease in blood pressure
• B
  Loss of water from body $\rightarrow$ Osmoreceptors $\rightarrow$ Neurohypophysis $\rightarrow$ $ADH$ $\rightarrow$ Reabsorption of water in distal parts of tubules $\rightarrow$ Increase in blood pressure
• C
  Loss of water from body $\rightarrow$ Osmoreceptors $\rightarrow$ Adenohypophysis $\rightarrow$ $ADH$ $\rightarrow$ Reabsorption of water in distal parts of tubules $\rightarrow$ Increase in blood pressure
• D
  Excess of water in body $\rightarrow$ Osmoreceptors $\rightarrow$ Adenohypophysis $\rightarrow$ $ADH$ $\rightarrow$ Water secretion in distal parts of tubules $\rightarrow$ Decrease in blood pressure
