Solution

The correct option is A Fats
Fats are broken down into free fatty acids (FFA) and triglycerides which can produce ATP through chemical reactions.
Fatty acids either circulate in the blood or are stored as triglycerides in adipose tissue and muscle.
Fat is a very energy dense nutrient, one gram of it provides nine calories of energy. 
Despite the large quantity of available energy that fat has it provides this energy at a much slower rate than carbohydrate. This is because the chemical reactions required for its breakdown are much more complex and time consuming.
