Final answer:
A growing teenage athlete requires b) 0.7–0.9 grams of protein per pound of body weight.
Step-by-step explanation:
To support growth and athletic training, a growing teenage athlete needs 0.7–0.9 grams of protein per pound of body weight. Dietary protein is essential for supporting metabolic reactions, muscle maintenance, growth, repair, and overall development during growth spurts, especially during infancy and adolescence. The increased need for protein is crucial as it provides the raw materials for producing new cells.
In adolescence, a higher intake of protein is needed to support the increased activity of muscle building and repair, especially in the case of athletes who are training regularly. For optimal health and performance, it's important that the diet of a teenage athlete includes a balanced amount of protein reflective of their increased needs.
Hence, the correct answer is Option B.
