Answer:
a ) Figurative language; metaphor
Step-by-step explanation:
A metaphor is a figure of speech that is used to make a comparison between two things that aren't alike but do have something in common. Unlike a simile, where two things are compared directly using like or as, a metaphor's comparison is more indirect, usually made by stating something is something else.
A metaphor states that one thing is another thing
It equates those two things not because they actually are the same, but for the sake of comparison or symbolism
If you take a metaphor literally, it will probably sound very strange (are there actually any sheep, black or otherwise, in your family?)
Metaphors are used in poetry, literature, and anytime someone wants to add some color to their language
