The correct option is A Oxytocin
The medicine given to Rekha for induction of labor is synthetic form of hormone oxytocin which acts on the uterine muscle and causes strong uterine contractions.

Somatostatin is a growth hormone-inhibiting hormone.
Prolactin is responsible for milk production.
Vasopressin or ADH is anti-diuretic hormone.
