Which of the following is an example of a formation in dance?

A circular formation in dance is characterized by dancers arranged in a ring or loop, creating a visually appealing and unified structure on stage. This formation allows for interaction among dancers as they maintain eye contact and can easily transition into various movements. The circular shape facilitates a sense of connection and equality among performers, enhancing the overall aesthetic of the choreography.

In contrast, binary formations typically refer to a two-part structure in dance, which does not describe a specific arrangement of dancers. Contrast pertains to differing movements or styles within a piece, while cyclical generally refers to repetitive sequences rather than a visual formation. Therefore, the circular formation stands out as a distinctly recognized arrangement used in various dance styles, making it the most appropriate answer.
