Correct answer & explanation

✓

Multicast support

AWS Transit Gateway supports multicast traffic by acting as a multicast router within a VPC, enabling you to send a single stream of data to multiple receivers across different VPCs. This is achieved through the creation of a multicast domain and the association of subnets as sources or members, using IGMPv2 for group membership management.
