In the exhibit, Site 1 is sending traffic on VLANs 100, 200, and 300.
The provider operating switch S1 must configure Q-in-Q tunneling to transport VLANs 100 and 200 to Site2.
The provider must configure switch S1 to block traffic received from site 1 on VLAN 300.

Which configuration accomplishes this goal?

A.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
customer-vlans [ 100 200 ];
}

B.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id [100 200];
interface {
ge-0/0/0.0 {
dot1q-tunneling {
block-vlans 300;
}
}
ge-0/0/1.0;
}

C.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0;
ge-0/0/1.0;
}
dot1q-tunneling {
block-vlans 300;
}

D.
{master:0}[edit vlans pv200]
user@S1# show
vlan-id 200;
interface {
ge-0/0/0.0 {
dot1q-tunneling {
customer-vlans [ 100 200 ];
}
}
ge-0/0/1.0;
}
