A and C eBGP (external BGP) by default requires two routers to be directly connected to each other in order to establish a neighbor adjacency. This is because eBGP routers use a TTL of one for their BGP packets. When the BGP neighbor is more than one hop away, the TTL will decrement to 0 and it will be discarded.
