Option 1 -> Places "hormonal balance" before completing the list of nutrients, disrupting the sentence structure.
Option 2 -> Correctly starts with the subject (nutrient-dense diet), completes the nutrient list, then explains the benefits in a logical flow.
Option 3 -> Starts with "healthy fats" without establishing context, creating a fragmented sentence.
Option 4 -> Begins with "hormonal balance" which is a benefit, not the subject, making the sentence illogical.
Hence, Option 2: (B), (D), (A), (C) -> This forms the complete sentence: "A nutrient-dense diet with adequate protein, fibre, healthy fats and complex carbohydrates not only keeps you full but also supports muscle mass, hormonal balance and a healthier metabolism." The sequence properly establishes the subject (the diet with all its components) followed by its multiple benefits connected with "not only...but also" structure -> correct
