Which of the following food sources provides the highest amount of protein per 100-gram serving?

Explanation:
Protein density by weight is what this question tests. Lean beef sirloin contains a much higher amount of protein per 100 grams than the other options because meat is primarily protein and fat with little carbohydrate. A 100-gram portion of lean beef delivers roughly 26–31 grams of protein, depending on cut and fat content. In comparison, eggs provide about 12–13 grams per 100 grams, lentils (when cooked) about 9 grams, and cooked rice only 2–3 grams. The difference in protein per weight means beef sirloin has the highest protein content per 100-gram serving among these choices.
