Which option shows the configuration syntax for a routed VLAN interface on an EX Series switch?

A.
interfaces {
vlan {
unit 10 {
family inet {
address 1.1.1.1/24;
}
}
}
}
vlans {
VLAN10 {
vlan-id 10;
routing-interface vlan.10;
}
}

B.
interfaces {
vlan {
unit 10 {
family inet {
address 1.1.1.1/24;
}
}
}
}
vlans {
VLAN10 {
vlan-id 10;
l3-interface vlan.10;
}
}

C.
vlans {
VLAN10 {
vlan-id 10;
family inet {
address 1.1.1.1/24;
}
}
}

D.
interfaces {
vlan {
unit 10 {
family inet {
address 1.1.1.1/24;
}
}
}
}
vlans {
VLAN10 {
vlan-id 10;
}
}

Explanation:
To do inter-vlan routing using routed VLAN interfaces (RVI) complete the steps below.

Step1:
Create a layer 2 vlan:
root# set vlans <vlan-name> vlan-id <vlan-id (1..4095)>

Step 2:
Create a logical layer 3 vlan interface:
root# set interfaces vlan unit <unit# (0..16385)> family inet address <ip address/mask>

Step 3:
Link the layer 2 vlan to the layer 3 vlan interface:
root# set vlans <vlan-name> l3-interface vlan.<unit# mentioned above>

NOTE: Repeat the above steps for all logical vlans on the switch.
