B Correct answer
Explanation

Transamination is the process where an amino group is transferred from an amino acid to a keto acid, forming a new amino acid. This is a key step in amino acid metabolism where nitrogen is ultimately converted to urea in the liver. Option B correctly identifies conversion of ammonia to urea (urea cycle), while C describes deamination (removal, not transfer). Option A is the reverse of what actually happens.
