Assuming that you don't want to negotiate an additional tunnel between Site A and Site C directly, you can do this simply by negotiating the appropriate IPsec policies on the two existing connections (and, of course, allowing forwarding of that traffic on Site B).
Between Site A and B you negotiate 10.0.0.0/8 on Site B and between Site B and Site C you negotiate 192.168.10.0/24 on Site B. This enables Site A and Site C to send traffic to those additional subnets to Site B, which then also can forward that traffic appropriately (it needs forward policies that allow traffic from 192.168.10.0/24 to 10.0.0.0/8 and vice-versa).
If you use IKEv2 you can simply add the additional subnets to Site B's local traffic selector for each of the two connections. And similarly on Site A and Site C for their remote traffic selectors, or you may configure 0.0.0.0/0 there to let Site B do the narrowing to the two subnets.

Sorry for the silly follow up... By "negotiate10.0.0.8", you mean adding another Phase 2?

No, adding another subnet to the traffic selector of the existing Phase 2/CHILD_SA. (Although, you can obviously add another CHILD_SA, but it's not really necessary.)
