What is the Class E airspace limit up to from the surface?

In the context of airspace classifications in the United States, Class E airspace extending from the surface has specific delineations based on visual navigation charts. The blue dashed lines indicate Class E airspace that begins at a specified altitude, typically above 1,200 feet above ground level.

On the other hand, the magenta dashed lines represent Class E airspace that extends from the surface to the overlying airspace. This configuration typically applies to areas where controlled airspace is needed at lower altitudes, providing a safe transition area for aircraft that are operating below 1,200 feet.

Understanding this distinction is crucial for pilots as it helps in the assessment of airspace requirements, navigation, and compliance with the corresponding rules for operating within these airspaces. Hence, the option identifying the magenta dashed line accurately describes the Class E airspace that starts from the surface level, making it the correct choice.
