Which plant-based dietary pattern is most likely to provide complete protein (all essential amino acids) without combining multiple plant foods in a single meal?

• A. Eating only rice, because single-grain diets universally supply all essential amino acids in adequate amounts.
• B. Relying exclusively on nuts like almonds as the single plant food source for all essential amino acids without supplementation.
• C. Avoiding legumes and depending on fruit alone, because fruits are high in protein quality comparable to meat.
• D. Consuming soy products (e.g., tofu, tempeh) because soy is a plant source with a relatively complete essential amino acid profile.
