Correct Answer:
D. of
This question tests the correct preposition to use with the verb “beware.”
- of is the correct answer. The verb “beware” means to be cautious and alert to the dangers of something. It is almost always followed by the preposition “of” when indicating the object of caution. The phrase “beware of” is an idiomatic expression meaning to be careful about or to be on guard against.
- to is grammatically incorrect in this context. “To” typically indicates direction or purpose.
- for is also incorrect. While one might “look out for” someone, “beware for” is not a standard English construction.
- on is grammatically incorrect. “On” usually indicates position or time.
