A company has three virtual private clouds $($VPCs$).$ VPCs A$,$ B$,$ and C have Classless Inter$-$ Domain Routing $($CIDR$)$ blocks that do not overlap. Both A and C have separate VPC peering connections with B$.$ However, A cannot communicate with C$.$ What is the simplest and most cost$-$effective way to enable full communication between A and C $?$ Add routes to B to enable traffic between A and C through B$.$ Add a peering connection between A and C$,$ and route traffic between A and C through the peering connection. Link all three VPCs through a transit VPC$,$ and route all traffic through the transit VPC$.$ Create VPC endpoints in A and C for the individual hosts that need to communicate with each other.
