Consider two operational configurations: Model A uses a single super-server (μ = 4/hr). Model B pools two parallel servers (μ = 2/hr each) into a single queue (M/M/2). Given an arrival rate λ = 3/hr, which statement correctly describes their operational dynamics? 

When multiple individual service queues are consolidated into a single pooled multi-server queue (M/M/c), average customer waiting time decreases primarily because total system capacity increases.
