What is the primary purpose of Carl's Jr.'s "Famous Star" promotion?

The primary purpose of Carl's Jr.'s "Famous Star" promotion is to highlight the flagship burger of the brand. The Famous Star is well known for its signature qualities, including a charbroiled beef patty, mayonnaise, lettuce, and tomato, which have made it a staple on the Carl's Jr. menu. By promoting this burger, the brand focuses on its core identity and the item that has drawn in customers for years. This strategy not only reinforces brand loyalty but also attracts new customers who may want to try the iconic product that represents the essence of Carl's Jr.

The other options do not align with the focus of the promotion, as they pertain to items not typically associated with the Famous Star branding. Promoting a salad option or a new drink line would not serve the same purpose of underscoring what has been positioned as a signature item in the Carl's Jr. offering. Similarly, emphasizing breakfast items would shift the attention away from the core burger identity that the Famous Star represents.
