What CLI command puts you into the policy configuration sub-mode, allowing you to add additional entries to the source, destination and/or service fields?

A.
set policy id x

B.
set multiple id x

C.
set policy id x multiple

D.
set policy from trust to untrust 10.10.10.0; 10.10.11.0 any any permit

Explanation:
Every policy has an ID number, whether you define one or the NetScreen device automatically assigns it. You can only define an ID number for a policy through the set policy command in the CLI: set policy id number … After you know the ID number, you can enter the policy context to issue further commands to modify the policy. For example :
Netscreen -> set policy id 1
Netscreen(policy:1)-> set src-address host2
