Read the excerpt from "once upon a time" and answer the question.

the alarms called to one another across the gardens in shrills and bleats and wails that everyone soon became accustomed to, so that the din roused the inhabitants of the suburb no more than the croak of frogs and musical grating of cicadas' legs.

what is the effect of using figurative language in this sentence?

a) by using simile to compare the alarms to croaking frogs or the sounds made by cicadas, the author conveys a severe absence of serenity in the neighborhood.
b) the author effectively uses alliteration to enhance the connection between the sounds of the alarms and the beginning sounds of the words that describe them.
c) by describing the alarms as having human characteristics while denouncing the intruders as less than human, the author effectively uses personification to convey a sense of irony.
d) the author uses a description of the alarms to symbolize the overstated degree of danger that the residents have assumed to the neighborhood watch.
