Which statement about energy density is correct?

Explanation:
Energy density means how many calories are in each gram of food. Fat provides about 9 kcal per gram, while carbohydrates and proteins each provide about 4 kcal per gram. Water has no energy. So fat is more energy-dense than both carbohydrates and proteins, which is why foods high in fat deliver more calories per gram. The other statements don’t fit because they claim carbs or proteins exceed fat in energy per gram, or because water adds energy, which it does not.
