Solution
The correct option is B Estrous
Females of most vertebrate species exhibit recurring periods of heightened sexual activity in which they are sexually attractive, proceptive and receptive to the males. In mammalian females (except humans, old world monkeys and apes) this periodic sex appeal is referred to as estrous or heat i.e., ready to accept a male and to mate. One or more estrous may occur during the breeding of a species. Prior to ovulation, the endometrium (uterine wall) thickens, in preparation for holding the fertilised ova. As the proliferation of uterine tissue reaches its peak, receptivity is highest. Thus, the correct answer is option D.
