B Correct answer
Explanation

This chemical is a protein, specifically the tryptophan synthase protein (or similar large protein structure). The sequence consists entirely of amino acid residues (methionyl, glutaminyl, arginyl, etc.) which are the building blocks of proteins. Proteins are long chains of amino acids, while carbohydrates, lipids, and vitamins have different chemical structures.
