Answer: (A)

Verified step by step guidance

1. Understand that sulfur is an essential mineral found in certain amino acids (e.g., methionine and cysteine) and is primarily associated with protein metabolism.
2. Recognize that high protein foods, such as meat, fish, eggs, dairy, legumes, and nuts, are rich in sulfur-containing amino acids.
3. Eliminate the other options by considering their macronutrient composition: high carbohydrate foods (e.g., bread, rice, fruits) and high fat foods (e.g., oils, butter) do not typically contain significant amounts of sulfur.
4. High fiber foods (e.g., vegetables, whole grains) may contain some sulfur, but they are not as concentrated in sulfur as high protein foods.
5. Conclude that high protein foods are the best source of sulfur due to their content of sulfur-containing amino acids.
