Fill in the blank with the correct preposition:

"How can you prevent him ________ doing things in his own way?"

Correct option is D

The verb "prevent" is always followed by the preposition "from" when referring to stopping someone from doing something. The structure is: prevent [someone] from [doing something].
Thus, the correct sentence is: "How can you prevent him from doing things in his own way?"
Explanation:
· "Prevent" means to stop something from happening or someone from doing something.
· The preposition "from" connects the object ("him") to the action ("doing things").
Hence, Option (d) "from" is the correct answer.
Information Booster
· "Prevent" is almost always followed by "from" in English grammar.
· The structure is: prevent + object + from + gerund (verb+ing).
· "Prevent" means to stop or hinder an action before it happens.
Additional Information
· Option (a) ("off") Incorrect because "off" indicates separation or removal, not prevention.
· Option (b) ("for") Incorrect because "for" indicates purpose or benefit, not stopping an action.
· Option (c) ("with") Incorrect because "with" indicates means or accompaniment, not restriction.
