Which configuration will accomplish this scenario?

You want to configure a redundant trunk group on a switch. You want ge-0/0/0.0 to be the default link; however, if ge-0/0/0.0 fails and the switch begins using ge-0/0/1.0, you want the switch to continue using ge-0/0/1.0 until ge-0/0/1.0 fails. Which configuration will accomplish this scenario?

A.
redundant-trunk-group {
interface ge-0/0/0.0 {
primary;
}
interface ge-0/0/1.0 {
primary;
}
}

B.
redundant-trunk-group {
interface ge-0/0/0.0;
interface ge-0/0/1.0;
no-preempt;
}

C.
redundant-trunk-group {
interface ge-0/0/0.0 {
primary;
}
interface ge-0/0/1.0;
}

D.
redundant-trunk-group {
interface ge-0/0/0.0;
interface ge-0/0/1.0;
}
