Which sentence is a simile?

• A. Time is like a thief.
• B. Time is a thief.
• C. Time steals like a thief.
• D. Time is a thief and a thief is time.

Answer: (A)

Simile uses like or as to compare two unlike things. The sentence Time is like a thief does that directly: it compares time to a thief by using the word like, suggesting time shares thief-like qualities without saying they are the same thing. The other options convey time as being a thief (metaphor) or describe actions in a way that isn’t a direct like/as comparison, so they aren’t similes.
