Final answer:
Boys aged 14-18 should consume (C) 70 grams of protein daily to support their rapid growth and body maintenance needs.
Step-by-step explanation:
The recommended daily amount of protein for boys aged 14-18 is 70 grams. Protein is a crucial nutrient, especially during periods of rapid growth such as adolescence. As indicated by various dietary guidelines, a balanced diet for this age group should include sufficient protein to support the body's growth and maintenance needs.
In addition to protein, a well-rounded diet should provide adequate amounts of fats, carbohydrates, vitamins, and minerals, along with sufficient water intake. It's important for growing adolescents to consume sources of high-quality protein like seafood, eggs, and other amino acid-rich foods to meet their daily requirements.
