Final answer:
A patient with hyposecretion of ADH would MOST LIKELY have oliguria (low urine output).
Step-by-step explanation:
A patient with hyposecretion of ADH would MOST LIKELY have oliguria (low urine output), which is option b. ADH, also known as antidiuretic hormone or vasopressin, plays a crucial role in regulating the amount of water reabsorbed by the kidneys. When there is a deficiency of ADH, the kidneys are unable to reabsorb enough water, resulting in reduced urine production.
