Which of the following is a visual tattoo used by those in the 5% gang?

The Playboy Bunny is a symbol often associated with the 5% Nation, also known as the Nation of Gods and Earths. Members of this group may use the Playboy Bunny tattoo to signify their affiliation and the lifestyle associated with the gang. This tattoo serves as a recognizable emblem that communicates membership within the gang and can also represent certain values or beliefs that align with the group's principles.

In contrast, the other symbols listed, like the heart or cross, do not have the same specific connotations related to the 5% gang. While they might be popular tattoos, they do not typically signify gang affiliation or carry the same specific cultural message. The skull, though associated with other gangs, is not specifically tied to the 5% Nation in the same way as the Playboy Bunny. Therefore, the Playboy Bunny is the most accurate representation of a visual tattoo used by those within the 5% gang.
