Final answer:
The advantage of an aerial service is faster delivery times, enabling expedited shipments by avoiding ground congestion, which increases delivery efficiency.OPTION A.
Step-by-step explanation:
An advantage of an aerial service is faster delivery times. Using aerial transportation means bypassing congested street networks and jam-packed freeways, which can heavily delay ground transport, thus reducing costs and increasing profits by ensuring more timely deliveries.
The proximity to uncrowded freeways or the availability of rail or water transport may also enhance transportation efficiency for a factory. However, the focus of the question is on aerial services, which excel in speed over distances where ground or water transport may be less efficient due to congestion or geographical barriers.
Phone service providers like AT&T, which have lost their monopolies due to technological advancements such as microwave and satellite transmission, have had to ensure reliability to stay competitive. Conversely, aerial services are often more reliable than many alternatives because they are less affected by localized problems such as road traffic.
