The correct answer is A. Increase her caloric intake to give herself more energy.
Step-by-step explanation
The human body works like a machine, hence we have to periodically check (visit the doctor) maintenance (have good habits of life) and in cases where it is damaged make repairs (follow medical treatments). Also, our body needs fuel to function, this fuel comes from the food we consume. For this, it is necessary to take into account the calories, a measure in which the energy value obtained from food is established. Therefore, in the case of Tiana who is going to make a bicycle trip with her father, the most important thing is that her diet gives priority to foods with high caloric levels because her muscles are going to need a lot of energy to perform basic operations of the body, and make that extra effort like riding a bicycle on long journeys. So, the correct answer is A. Increase her caloric intake to give herself more energy.
