How are messages routed to the cloudhub workers as messages are received by the VM Listener?

Refer to the exhibit.

This Mule application is deployed to multiple Cloudhub workers with persistent queue enabled. The retrievefile flow event source reads a CSV file from a remote SFTP server and then publishes each record in the CSV file to a VM queue. The processCustomerRecords flow’s VM Listner receives messages from the same VM queue and then processes each message separately.

How are messages routed to the cloudhub workers as messages are received by the VM Listener?
A . Each message is routed to ONE of the Cloudhub workers in a DETERMINSTIC round robin fashion thereby EXACTLY BALANCING messages among the cloudhub workers
B . Each messages routes to ONE of the available Clouhub workers in a NON-DETERMINSTIC non round-robin fashion thereby APPROXIMATELY BALANCING messages among the cloudhub workers
C . Each message is routed to the SAME Cloudhub worker that retrieved the file, thereby BINDING ALL messages to ONLY that ONE Cloudhub worker
D . Each message is duplicated to ALL of the Cloudhub workers, thereby SHARING EACH message with ALL the Cloudhub workers.

Answer: B
