Explanation:

• Lipolysis is the breakdown of lipids (fats), not related to amino groups.
• Deamination specifically refers to the removal of an amino group (\(-NH_2\)) from an organic molecule (like an amino acid).
• Transamination is the transfer of an amino group, not its removal.
• Pyruvate formation is part of cellular respiration (e.g., glycolysis), unrelated to amino group removal.

Answer:

B. deamination
