B Correct answer
Explanation

Nonpolar amino acids have hydrophobic side chains that do not carry any electrical charge. These side chains are typically composed of carbon and hydrogen atoms, making them uncharged and water-repellent. Aromatic side chains can be nonpolar, but 'uncharged' is the more fundamental and accurate categorization.
