PT60.S1.Q22 - One of the most useful social conventions

I was wondering why you can't use C as a contrapositive?
I interpreted C as Universal feature + not invention -> innate ability

/innate ability -> /universal feature or /not invention
It says money is an artificial invention unlike language, which is an innate ability
And it says money is universal

So couldn't money -> /innate ability -> /universal feature or /not invention, and since it is a universal feature, can conclude /not invention? Or is the mistake that I am interpreting /not invention to mean invention, when it simply means it's not not an invention?

Thanks.

C cannot be an answer because the stimulus states that "money is an artificial human invention" yet C only applies to things that are "not invention".
For this question, it's easy to get tripped up by the premises. Personally, I'd recommend you to skim over the premises and place your focus on the conclusion.
"Independent" translates to "not dependent", right? A states that exactly, "not...influenced by other".
Hope this helped.
