Which CAP charges $100 at the national level?

The correct answer is related to the affiliation of the Civil Air Patrol (CAP) with its membership and program fees. The green CAP, often referred to in the context of the Civil Air Patrol, represents a specific type of membership or program that is charged at a national level. The $100 fee typically refers to the membership dues that help support national programs, operations, and member services.

In the context of the available choices, blue, white, and red do not specifically denote a fee structure or membership type that correlates with the $100 charge at the national level. Each color usually represents different roles, achievements, or uniforms within the organization, but they are not associated with a national fee structure that stands out as the green CAP does. Therefore, the identification of the green CAP as the one that charges $100 at the national level is accurate because it signifies a formal and standardized fee for membership.
