• D. Mutual behavior of members of a species

Answer 1

Answer: (D)

Pheromone is a substance which is secreted by an individual on the skin surface to sexually attract an individual of another sex. Pheromones secreted by one individual are perceived by another individual through smell receptors. So, individuals of opposite sex are attracted towards each other. Hence, the odour of pheromones affects the mutual behaviour of members of a species.

So, the correct answer is 'Mutual behaviour of members of a species'.
