On weekdays, what times are visitors allowed on-board?

The correct answer reflects the established visiting hours for visitors on board during weekdays, which are from 1330 to 2200. This timeframe is typically set to facilitate operations and ensure that the ship is secure during critical working hours while allowing visitors access during a more suitable time in the afternoon and evening.

By beginning at 1330, it allows visitors to come on board after most daily operations have settled down and typically aligns with shift changes, ensuring that staff can accommodate guests without interfering with operational duties. The end time of 2200 provides a reasonable window for visitors while still allowing for evening preparations for the crew.

In contrast, the other options either begin too early or conclude too soon or do not take operational hours into account. The hours outlined in those choices may conflict with the ship's operational readiness or security protocols, making them unsuitable for visitor access during those times.
