The myths are of different types some embodying a belief regarding some fact, phenomenon, or experience by personifying the forces of nature or some relating a scared narrative relating to a god, hero or regarding the origin of a particular belief or world, etc.
As per the question, the purpose of the story of Echo(myth) is 'to illustrate the natural occurrence of echoes and containing the religious elements as well'. As per the Greek mythology, Echo is described as the mountain nymph and Zeus(the god of the sky) was fascinated towards nymphs and therefore, he met them often due to which his wife Hera got jealous of nymphs and cursed them(only able to replicate the last words just said by another person). Later, Nymph repeats the words of Narcissus but Narcissus's dejection left her in distress as Narcissus fell in love with himself and led to death. Echo couldn't help it out but only mourning. Thus, option A is the correct answer.
