Refer to the exhibit. VTP has been enabled on the trunk links between all switches within the TEST domain. An administrator has recently enabled VTP pruning. Port 1 on Switch 1 and port 2  on Switch 4 are assigned to VLAN 2. A broadcast is sent from the host connected to Switch 1.  Where will the broadcast propagate?（）

A.Every switch in the network receives the broadcast and will forward it out all ports.

B.Every switch in the network receives the broadcast，but only Switch 4 will forward it out port 2.

C.Switches 1，2，and 4 will receive the broadcast，but only Switch 4 will forward it out port 2.

D.Only Switch 4 will receive the broadcast and will forward it out port 2.
