So... A couple questions for you.
1. If it was a question in the exam, should you be talking about it in detail? (NDA?)
2. If you found the exact question in your study materials, should you really be presenting that information? (Again, NDA?)
Conceptually, it's ok to talk about things, but the NDA is an agreement about NOT disclosing specific information that's in the exam!
The catch in the question is talking about the other queues "not congested". Queuing happens during congestion. So any command referencing queuing would not be counted there.
I'll let you talk yourself through the rest of the way, but some advice going forward.... In a forum hosted by Cisco, and that has many Cisco employees on here, particularly many within the certification structure, I'd suggest not breaking NDA in the future. Otherwise you may find your testing to be accomplishing nothing!
OK, The question image is from pass4sure. This seems to border on a traffic shaping question, read this link
To specify or modify the maximum number of packets the queue can hold for a class policy configured in a policy map, use the queue-limit policy-map class configuration command.
queue-limit number-of-packets "
Read this link on bandwidth and priority and police
If a bandwidth or priority class should not exceed its allocated bandwidth during periods of no congestion, you can combine the priority command with the police command. This configuration imposes a maximum rate that is always active on the class. Choosing to configure a police statement in this configuration depends on the policy's objective.
