Which of the following sentence(s) use the word PASSING incorrectly or inappropriately?

> 
> (a) She did not have **passing** marks in mathematics.
> 
> 
> (b) The mad woman was cursing everybody **passing** her on the road.
> 
> 
> (c) At the birthday party, all the children enjoyed a game of **passing** the parcel.
> 
>

I'm not passing on my assignment to you guys. Me and my friend disagree on the answer and we need to confirm.

I say usage in option (b) is incorrect. The correct sentence should be

> 
> (b)The mad woman was cursing everybody **passing by** on the road.
> 
> 
> Reason: "passing her" would mean that everybody is passing through her which doesn't make sense.
> 
> 
> 

My friend says usage in option (a) is incorrect. The correct sentence should be

> 
> (a) She did not have **pass marks** in mathematics.
> 
> 
> Reason: "pass marks" is the correct usage not "passing marks"
> 
> 
> 

Kindly tell which is wrong and why? (It is possible that more than one are wrong)
