Estrous cycle is a reproductive cycle of females of non-primate vertebrates. The gap between two estrus period is known as estrous cycle. The females are highly receptive during estrus period. It is an indication of breeding period because one or more periods of estrus may occur during the breeding season of a species. Some animals like dogs are monoestrous as they have only one estrous phase in their breeding cycle. Males can recognize a female in heat by smell of pheromones.

So, the correct answer is option C.
