Non-price rationing system is commonly done by queuing (to resolve rationing problems brought by price ceilings) and by coupons (to restore buyer equilibrium). Favored customers who received special treatment from dealers when there is an excess demand, which means: owners giving goods and services to their friends, is another non-price rationing mechanism.
I believe the answer is: B)first-come, first-served
In a non-pricing system, the sellers of the product could never change the price of their product since it's already fixed (just like what we see on departement stores). This make the consumers lose the power to bid and they have to come before any other consumers obtain the product in order to get it.
