A Correct answer
Explanation

The corpus luteum secretes progesterone, which maintains the endometrial lining for potential embryo implantation and supports early pregnancy until the placenta takes over. This function is essential for 'retention of pregnancy'. Childbirth is triggered by oxytocin, ovulation is caused by LH surge, and milk production is stimulated by prolactin - not corpus luteum functions.
