• A. Carbohydrates
• B. Fats
• C. Proteins
• D. Minerals

Answer: (C)

The main idea here is that building muscle hinges on providing enough protein to support muscle repair and growth after resistance training. Protein supplies the amino acids your muscles need to synthesize new tissue, so without enough protein, muscle gains can stall even if you’re lifting regularly. On a vegetarian diet, you can still meet these needs, but you have to ensure total daily protein is sufficient and that you’re getting a good mix of essential amino acids. If her protein intake has been too low or too uneven across meals, muscle protein synthesis won’t be maximized, leaving her with minimal gains. Carbohydrates and fats are important for energy and overall health, but they don’t directly trigger muscle-building tissue in the same way protein does. Minerals are essential for various bodily functions, yet they aren’t the building blocks of muscle tissue itself. Practical takeaway: aim for an adequate daily protein intake (roughly 1.6–2.2 g per kg of body weight for someone doing regular strength training), and spread protein across meals with a variety of plant sources to cover all essential amino acids. Include soy products, dairy or eggs if allowed, and other plant proteins like legumes, grains, and nuts to meet the needs.
