Verified step by step guidance

Step 1: Understand the context of the question. Carbohydrates are one of the macronutrients that provide energy to the body. The energy content of macronutrients is typically measured in calories per gram.

Step 2: Recall the standard caloric values for macronutrients. Carbohydrates and proteins each provide 4 calories per gram, while fats provide 9 calories per gram. Alcohol provides 7 calories per gram.

Step 3: Identify the correct caloric value for carbohydrates based on the standard values. Carbohydrates specifically supply 4 calories per gram.

Step 4: Compare the given options (7 calories, 4 calories, 9 calories, 2 calories) to the standard caloric value for carbohydrates. Select the option that matches the correct value.

Step 5: Confirm your understanding by reviewing the energy contributions of other macronutrients to ensure clarity and avoid confusion in similar questions.
