Answer :
Final answer:
The visibility range for class A and C lighting at night is typically greater than 2,000 feet, which exceeds the distances provided in the multiple-choice options. These lights are used in aviation and maritime safety and are subject to standards that ensure they are visible from substantial distances to provide adequate warning and identification.
Explanation:
The visibility distance for class A and C lighting at night is a factor of safety in aviation and maritime navigation, and as per regulations, these lights should be visible at a minimum distance to provide adequate warning and identification. While the question lacks context on which regulatory body or specific standards we are referring to, as a general rule in the field of transportation, lights should be visible from substantial distances to ensure safety.
In this context, typically navigational lights such as those on aircraft (class A) and on boats or ships (class C) are expected to be visible from distances much greater than those offered as options in the question. In aviation, for example, anti-collision lights need to be visible for at least 3 miles (approximately 4800 feet) during night time, and even more during day time. Similarly, in maritime contexts, visibility distances are regulated by international standards and would exceed the distances provided in this MCQ.
