Step 1: Understanding Prepositions of Fault:
When talking about finding fault with someone, the correct preposition is "with." We use "with" to indicate the person being criticized. Step 2: Analyzing the Options:
- By: This is incorrect because "by" is not used when referring to fault-finding in this context.
- In: This is incorrect because "in" is used for physical locations or situations, not for fault-finding.
- With: This is the correct preposition to use with "finds fault," indicating the person being criticized.
- To: This is incorrect because "to" is used to indicate direction, not fault-finding. Step 3: Conclusion:
The correct preposition is with.
