Which organization does the sorority notably support among others?

The sorority Sigma Gamma Rho Sorority, Inc. notably supports the United Negro College Fund (UNCF). This organization plays a critical role in providing scholarships and financial assistance to students attending historically black colleges and universities (HBCUs) and other educational institutions. By aligning with the UNCF, Sigma Gamma Rho emphasizes its commitment to educational advancement and empowerment within the African American community. This support reflects the sorority's mission to foster academic excellence, leadership development, and the promotion of social justice.

In contrast, while the other organizations mentioned may align with philanthropic interests, they do not specifically represent the primary focus of Sigma Gamma Rho's initiatives or community involvement regarding educational support and advocacy for African American college students.
