Which of the following contains a reference to the auditory or hearing sense?

a.) the art of literature stands apart from among its sisters, because the material in which the literary artist works is the dialect of life; hence, on the one hand, a strange freshness and immediacy of address to the public mind, which is ready prepared to understand it; but hence, on the other, a singular limitation.
b.) � no inscrutable shadow, as in painting; no blank wall, as in architecture; but every word, phrase, sentence, and paragraph must move in a logical progression, and convey a definite conventional import.
c.) � restore to them their primal energy, wittily shift them to another issue, or make of them a drum to rouse the passions.
d.) the sister arts enjoy the use of a plastic and ductile material, like the modeller's clay; literature alone is condemned to work in mosaic with finite and quite rigid words.
