Which of the following is a trademarked symbol of Alpha Kappa Alpha Sorority?

The crest, also known as the shield, is indeed a trademarked symbol of Alpha Kappa Alpha Sorority. It serves as an official emblem that represents the organization’s values, history, and commitment to its mission. Each element of the crest carries significant meaning and reflects the sorority's dedication to scholarship, service, and sisterhood.

The ivy leaf, while an important symbol within AKA, specifically represents growth and strength, particularly among women of color, but it is not trademarked in the same way the crest is. Similarly, Beulah Burke is recognized for her foundational role in the sorority, particularly as one of its founders, but she is not represented by a trademarked symbol. Therefore, the correct answer aligns with the unique identification and branding associated with the organization, solidified by the crest as an official and protected emblem.
