Shouldn't that ";" be a ":"?

Anyway, now to your question. I think you should use the ProxyCommand
option for ssh. If A, B and C are fixed. You can put the folowing in
your ~/.ssh/config.
# using B as proxy to C
Host C
User useronC
ProxyCommand ssh -q B nc %h 22
Host B
User useronB
This will let you do the following:
$ ssh -X B
$ ssh -X C
