The correct answer is A. Adequacy
Explanation:
In nutrition, the term "adequacy" refers to the necessary amount of nutrients or food a person needs to consume to be healthy which depends on the physical activity, requirements and medical conditions of the individual. In this way, Jamie's diet lacks adequacy because as an athlete she required 2.800 kilocalories; however, she is only consuming 1.600 kilocalories each day and this means she is not consuming the necessary amount of nutrients and food and therefore her diet is inadequate for her requirements and physical activity level.
