Which of the following is NOT a type of burger served at Carl's Jr.?

The choice indicating the Veggie Burger as the option that is not a type of burger served at Carl's Jr. is accurate. Carl's Jr. is known for its variety of traditional meat-based burgers, and while they do offer a selection of vegetarian options, the specific "Veggie Burger" is not typically listed among their main burger lineup.

The other options are well-established menu items at Carl's Jr. The Double Cheeseburger features two beef patties and cheese, appealing to those seeking a hearty option. The Western Bacon Cheeseburger combines a beef patty with crispy bacon, onion rings, and barbecue sauce, providing a unique flavor profile that is popular among customers. Additionally, the Grilled Chicken Burger is part of the grilled offerings, catering to those looking for a lighter meat option.

Overall, the focus on these specific traditional and grilled burger options, alongside the lack of a dedicated Veggie Burger on the current menu, clarifies why this choice is correct.
