Azure Service Bus: single producer and multiple consumers scenario for Service Fabric applications

I am new to Azure Service Bus and having a difficult time wrapping my mind around a few concepts, so any help is greatly appreciated!

I have distributed (Service Fabric) applications, say A and B where each consists of instances running on different nodes (say A1, A2, B1, and B2). There are two scenarios that I need to support:

1. a producer publishes a single message and EVERY consumer receives it (A1, A2, B1, B2)
2. a producer publishes a single message and a single instance per application receives (say A2 and B1) 
   

Should I be publishing a message to a queue and then forward it to another set of queues?

Thank you in advance and my apologies if I didn’t ask this in the right forum.
