I think you're totally wrong _____ her - she's nice!

• A. About
• B. To
• C. With
• D. For

Answer: (A)

The idea being tested is how we pair the adjective wrong with a preposition to show what idea or belief is mistaken. When you want to say your view about someone or something is incorrect, you use wrong about followed by the topic.

In this sentence, your belief about the person is being challenged: you think she’s not nice, but the speaker says that belief is incorrect. That’s why about is the natural choice here — it marks the topic of the mistaken belief.

The other prepositions don’t fit the sense here. To someone would imply directing an action toward them, with someone would suggest a problem in the relationship, and for someone would mean something like being unsuitable for them, none of which express “my view about her is wrong.”
