Glacial? Is that like acetic acid?
Dang it! I must not be on the American side only anymore!
Wait. B&H has it.
Why would they produce something like that?
May as well save on the shipping and use vinegar!
I always use indicator stop bath.
C's the right answer.
The others are are too weak to stop it fast enough.
You can get by with it less strong on paper - or even do without (shortens your fixer a mite though) cause it's not as critical to stop the processing that quickly.
But with film you don't want it developing even another 5 seconds if you want consistency (and you want consistency).
Especially if you're push processing it, running a bit hot (sometimes, you have to make do with the temperature you have), or using a extra powerful or concentrated developer.

One part glacial to 20 parts water. This chemical is used to stop the action of the developer, either paper or film, black and white only. It works by neutralizing the alkaline nature of the developer. It does not need to be any stronger than this to work and would be very stinky to work with any stronger.
