1. Confirm the OpenVPN systems from sites B & C can ping each other. 
They should be able to from what I have seen.

2. I believe your hosts on either site B, C or both do not have a
route for the other site that points to the OpenVPN system at their
site.  Have some one at each site tracert/traceroute to the other site
to see where the routing is not correct.
