Solution
The correct option is C Decrease in secretion of ADH from pituitary During dehydration, there is a loss of fluids from the body. This results in an increase in the solute concentration inside the body and hence increases the osmolarity of the body fluids. This decrease in the osmolarity further decreases the release of ADH into the body from the pituitary.
So, the correct answer is 'Decrease in the secretion of ADH from pituitary'.
