Answer:

The correct answer is option b, that is, inhibition of vasopressin.

Explanation:

Vasopressin also called ADH or anti-diuretic hormone results in the resorption of water by the collecting duct and the distal convoluted tubule of the nephron, and thus, minimizes the reduction of water via urine. Consuming ethyl alcohol results in the prevention of the secretion of ADH that results in frequent urination.
