which configuration example will allow you to ensure that the node with the higher priority will become primary for your RGs other than RG0?

If both nodes in a chassis cluster initialize at different times, which configuration example will allow you to ensure that the node with the higher priority will become primary for your RGs other than RG0?

A.
[edit chassis cluster]
user@host# show
redundancy-group 1 {
node 0 priority 200;
node 1 priority 150;
preempt;
}

B.
[edit chassis cluster]
user@host# show
redundancy-group 1 {
node 0 priority 200;
node 1 priority 150;
monitoring;
}

C.
[edit chassis cluster]
user@host# show
redundancy-group 1 {
node 0 priority 200;
node 1 priority 150;
control-link-recovery;
}

D.
[edit chassis cluster]
user@host# show
redundancy-group 1 {
node 0 priority 200;
node 1 priority 150;
strict-priority;
}
