The correct answer is C. A simile uses as or like to make a comparison and a metaphor doesn't.
Step-by-step explanation:
Both simile and metaphor are figures of speech widely used in literature such as poetry to create a comparison between two ideas, concepts, people, etc. This means they both had the same objective and therefore are used similarly. Despite this, simile differs from metaphor because in simile the comparison is explicitly stated by the use of words such as "like" or "as" for example in "Your eyes are like stars", but this is not necessary in the case of metaphors, for example, "Your eyes were stars" is a metaphor.
