D.
If both assertion and reason are false
It is not oxytocin, but the hormone vasopressin (also known as antidiuretic hormone, ADH) because it reduces the volume of urine by increasing the reabsorption of water from the urine in the distal convoluted tubules, collecting tubules and collecting ducts in the kidney. It does so by rendering the walls of those tubules permeable to water. Failure of secretion of vasopressin leads to a reduced renal reabsorption of water and a consequent elimination of a large volume of very dilute (hypotonic) urine.
Oxytocin is another hormone released by the posterior lobe of pituitary gland. Oxytocin contracts the mammary glands, smooth muscles of uterus. Uterine contractions, stimulated by oxytocin at the end of pregnancy, help in the child-birth or parturition, hence also called birth hormone. The oxytocin - induced contractions of the mammary gland muscles help in the flow of stored milk from the mammary glands, hence also called milk ejection hormone.
