• B. Menstruation at the end of the estrous cycle

Answer 1

The correct option is B Menstruation at the end of the estrous cycle

• Animals that have estrus cycles resorb the endometrium if conception does not occur during that cycle.
• Animals that have menstrual cycles shed the endometrium through menstruation if conception does not take place.
• So, the correct option is 'Menstruation at the end of the estrus cycle'.
