Final answer:
The correct option is A). Cinemas offering discounts on slow days are addressing the perishability characteristic of services, which is the inability to store services for future use.
Step-by-step explanation:
Cinemas offering serious discounts, like half-price on 'Cheapy' Tuesday, are managing the perishability characteristic of services. This is because the service must be consumed at the time it is offered, and if not consumed—such as a seat in a cinema on a slow day—it can't be stored for future use, resulting in a potential loss. To mitigate this loss, cinemas employ pricing strategies during low-demand periods to encourage consumption, thereby managing the perishability aspect of their service.
