Prepositions?

Hi teachers,

Our teacher asked a preposition question today. I think it was very hard question.

A Japanese stem cell scientist _______ the heart of a scandal ______ false claims and fabricated research has resigned.

A) in / with
B) at / over

My option was A. But teacher said it wasn't correct and he didn't explain why it was incorrect. Prepositions are very difficult subject for me. I need an explanation here.

The answer is B. Very often there is no sound explanation. We simply have to accept that certain words are used with certain prepositions,
