Final answer:
The VFR minimum distance over built-up areas is not lower than 1,000 feet above the highest obstacle within a 2-mile radius, and over non built-up areas, it is not lower than 500 feet within a 2-mile radius, making option A correct.
Step-by-step explanation:
The VFR (Visual Flight Rules) minimum distance requirements for aircraft flying over different types of terrain are specified to ensure safety and prevent collisions with obstacles. For built-up areas, the regulatory requirement is to fly at an altitude not lower than 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet. Conversely, when flying over areas that are not built-up, aircraft should not be lower than 500 feet above the highest obstacle within a horizontal radius of 2,000 feet. Therefore, the correct answer to the question is option A) 1000, 2-mile, 500, 2-mile.
