The delivery time window provided must be a ______-hour window.

• A. 2-hour window
• B. 1-hour window
• C. 4-hour window
• D. 3-hour window

Answer: (A)

Two-hour delivery windows balance reliability and feasibility in scheduling deliveries. A two-hour commitment gives customers a concrete, useful ETA while giving the carrier enough time to plan routes, manage loading, and account for typical delays. If the window were only one hour, the delivery plan would be extremely tight and harder to guarantee, increasing the risk of missed deliveries. A four-hour window, on the other hand, becomes vague for the customer and complicates precise routing and time management. A three-hour window might be workable in some contexts, but the standard here targets two hours to provide a practical middle ground that improves punctuality and customer satisfaction.
