Answer:
Hyperbole
Step-by-step explanation:
By using the process of elimination, the only viable answer turns out to be that the sentence is a hyperbole.
The sentence is not a simile because the sentence is not comparing something to anything else, it is simply a statement that all men are created equal.
The sentence is not an allusion because an allusion is a reference to a particular literary work or significant event, which is not present in the statement.
Therefore, the answer must be hyperbole because one, the other answers don't make sense, and two, because a hyperbole is an over-exaggeration of a particular matter and the statement, "all men are created equal," is an over-exaggeration due to the fact that the American colonists did not treat men of different races other than white as equals for several centuries to come.
