Regarding the obstruction located 7 SM west of McKinney Airport, which statement is correct?

1. the obstruction is unlighted

2. the obstruction has high-intensity lights

3. the elevation of the top of the obstruction is 729 feet AGL

4. the obstruction is seasonal

The correct answer is: the obstruction has high-intensity lights

The statement indicating that the obstruction has high-intensity lights is correct because obstructions must be adequately marked and lighted according to FAA regulations, especially if they present a significant hazard to aviation. High-intensity lights are typically used for large obstructions or those located in areas where they are likely to be encountered by aircraft, helping to enhance visibility during both day and night operations. This ensures pilots can identify and navigate around potential hazards more easily. Other statements may misrepresent the characteristics of the obstruction. For example, if the obstruction were seasonal, it would have specific seasonal attributes which would be less common. Knowing whether an obstruction is unlighted or has different types of lighting can also depend on various factors such as its height and geographical location, which further emphasizes the importance of accurate obstacle assessment for safe flight operations.
