Answer: D) hyperbole.
Explanation: A hyperbole is a type of figurative language that consists in exaggerating an event or a statement. The given sentence is a clear example of a hyperbole because it is an exaggeration. It isn't a simile or a metaphor because they are comparisons between elements that aren't obviously related (it can be a direct or indirect comparison), and it isn't a personification neither because it doesn't give human characteristics to non human objects.
