b. increased irritability
c. steady energy
d. sudden fatigue

Explanation:

First Question:

To determine the nutrient for muscle repair/growth, recall: Carbohydrates (energy), Fats (energy/storage), Fiber (digestion), Protein (builds/repairs tissues like muscles). So Protein is key.

A balanced meal provides nutrients steadily. Higher sugar crashes (unbalanced, e.g., high sugar), increased irritability (unbalanced, low nutrients), sudden fatigue (unbalanced) are negative. Steady energy comes from balanced nutrients.

Answer:

d. Protein
