c为什么不对？ 看起来更加对称，如果把impede改回diminish 是否就没问题了？

You are right, if in C 'impede' is replaced by 'diminish', C is a perfect answer.
In choice C, 'impede' which means 'To retard or obstruct the progress of ' distorts the meaning of 'diminish' which means 'To make smaller or less '.
This is the only reason that C is wrong.

'impact on'= 'have a impact on',
