The question asks for the total kilocalories in a meal given its macronutrient grams: 60 g carbohydrate, 35 g protein, and 25 g fat.

Each macronutrient contributes energy per gram: carbohydrates and protein provide 4 kcal/g, while fat provides 9 kcal/g.

Option by option analysis:

- 480 kcal: This would imply a lower total than correct. If we sum correctly, 60 g carb (60 × 4 = 240 kcal) plus 35 g protein (35 × 4 = 140 kcal) already equals 380 kcal, and adding fat would push the total higher. Therefore 480 kcal is too small and reflects undercounting either fat energy or both carbohydrates and protein.

- 555 kcal: This is closer but still incorrect. The exact calculation is 240 (carbs) + 140 (protein) + 225 (fat) = 605 kcal. The difference of 50 kcal suggests either miscalculation of fat energy (25 g × 9 kcal/g = 225 kcal, not 275) or miscounting one macronutrient.

- 605 kcal: This matches the precise energy calculation. Carbohydrates: 60 × 4 = 240 kcal; Protein: 35 × 4 = 140 kcal; Fat: 25 × 9 = 225 kcal; Total = 240 + 140 + 225 = 605 kcal.

- 655 kcal: This would require overestimating one or more components. If fat were counted as 9 kcal/g correctly, the sum would not reach 655 with the given gram amounts, since the correct total is 605 kcal. This option suggests an error in fat value or miscounting another macronutrient.

In summary, applying standard Atwater factors (4 kcal/g for carbohydrate and protein, 9 kcal/g for fat) yields a total of 605 kcal for the dish, so the correct choice is the option that lists 605 kcal.
