Which of the following is a method of financing for FBLA?

Membership dues are indeed a fundamental method of financing for FBLA chapters. These dues are collected from members and play a crucial role in supporting the operational costs of the organization. By paying membership dues, members contribute to funding various activities and resources, such as conferences, materials, and chapter events. This structured approach allows FBLA to maintain its programs and outreach effectively.

While the other options can also serve as potential funding sources, they are typically supplementary. Student sponsorships, online fundraising, and local business partnerships can enhance the financial standing of an FBLA chapter, but membership dues provide a consistent and formalized stream of revenue that is integral to the organization's sustainability.
