Answer 2

Answer:

answer is : B 4

Explanation:

Acetic acid, systematically named ethanoic acid, is a colourless liquid organic compound with the chemical formula CH₃COOH. When undiluted, it is sometimes called glacial acetic acid. Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water.
