Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Option C states 'Tonic acid: Leather' which is incorrect. The correct pairing should be 'Tannic acid: Leather' because tannic acid (or tannins) are used in leather tanning to preserve and soften animal hides. 'Tonic acid' appears to be a typo or error - there is no such compound used in leather processing. Options A and B (Acetic acid: Vinegar, Amino acid: Proteins) are correct pairings.
