Correct option is A
Correct answer: A
Correct sentence
If I owned a zoo, I might let people interact with the animals more.
Explanation
This is a hypothetical (unreal) condition, so it should follow the second conditional structure:
· If + past simple → would/might + base verb
· Incorrect: “If I own a zoo…”
· Correct: “If I owned a zoo…”
Error analysis
Part A: Incorrect – “own” should be “owned” for hypothetical condition.
Part B: Correct – “might let people” is proper.
Part C: Correct – “interact with” is correct usage.
Part D: Correct – “the animals more” is fine.
Conclusion
Error is in Part A due to incorrect conditional tense usage.
