On Sectional Aeronautical Charts, the use of blue and magenta colors is important for identifying different types of airports and their operational statuses. The correct statement highlights that airports with control towers that are situated beneath Class B, C, D, and E airspace are indicated in blue. This blue color coding signifies that these are controlled airports, which have air traffic control facilities in place to manage aircraft operations.

Class B, C, D, and E airspace recognizes the environments where air traffic is either highly regulated (Class B and C) or somewhat less controlled (Class D and E). The blue highlights these controlled airports clearly to pilots, allowing them to understand the airspace environment they are entering or navigating through.

In contrast, magenta is used on these charts to identify uncontrolled airports or those lacking a control tower. This delineation helps to create a clear visual representation of the varying classifications of airspace and the associated airport operations, which is crucial for pilot navigation and flight safety.

Understanding these distinctions is essential for pilots as they plan their routes, communicate with air traffic control, and adhere to specific operational procedures based on airport classifications.
