Option 1: (A), (C), (B), (D) -> Creates a fragmented sentence that doesn't follow logical grammatical structure.
Option 2: (D), (C), (A), (B) -> Starts correctly but ends awkwardly with "but" hanging without proper continuation.
Option 3: (B), (D), (C), (A) -> Forms: "Dozens of diets are touted as the best, but it's easy to lose track of the fact that healthy eating needs to be about overall wellness, not just weight loss" - a complete, meaningful sentence with proper flow.
Option 4: (C), (A), (D), (B) -> Begins with "that" without an introductory clause, making it grammatically incorrect.
Hence, Option 3: (B), (D), (C), (A) -> This arrangement creates a coherent sentence that starts with a contrasting premise about diet trends, then transitions with "but" to introduce the main point about losing sight of the true purpose of healthy eating, which is overall wellness rather than just weight loss. The sentence follows proper grammatical structure with logical connectors. -> correct
