Answer 1

The correct option is C Vasopressin


Oxytocin

Oxytocin is also known as the birth hormone. It causes contraction of the uterine wall, which leads to parturition.

Vasopressin

Vasopressin facilitates water reabsorption from latter parts of the tubule, thereby preventing diuresis[excess urine production]. Thus, it is also known as antidiuretic hormone (ADH).

Adrenaline

Adrenaline is a hormone secreted by the adrenal gland, that prepares the body to fight or flight.

Calcitonin

Calcitonin is a hormone secreted by C-cells of the thyroid gland. It helps in maintaining blood calcium levels.

Final answer
Option(b) Vasopressin
