To determine which nutrient provides the most food energy, we need to look at the number of calories provided by each nutrient. 
Carbohydrate provides 4 calories per gram (25 g * 4 cal/g = 100 calories).
Fat provides 9 calories per gram (15 g * 9 cal/g = 135 calories).
Protein provides 4 calories per gram (18 g * 4 cal/g = 72 calories).
Water provides 0 calories per gram (100 g * 0 cal/g = 0 calories).
Therefore, it can be seen that fat provides the most food energy, so option D is the correct answer. Option A is incorrect as protein only provides around 29% of the total calories. Option B is also incorrect as carbohydrate provides less calories than fat. Option C is incorrect as water does not provide any calories.
