Explanation

A: There is a host on port A1 (of Switch A) that is in the FF14::1 group. So Switch A will forward this packet on the A1 port. D: Switch A learns through MLD snooping (see note below) that through port B2 and through Switch C there is a host that is in the FF14::1 group. So Switch A will forward this packet on the Note: Multicast Listener Discovery (MLD) snooping constrains the flooding of IPv6 multicast traffic on VLANs on a switch. When MLD snooping is enabled on a VLAN, a Switch examines MLD messages between hosts and multicast routers and learns which hosts are interested in receiving traffic for a multicast group. Based on what it learns, the switch then forwards multicast traffic only to those interfaces in the VLAN that are connected to interested receivers instead of flooding the traffic to all interfaces.
