Correct answer
CAlanine
Step-by-step explanation
Kjeldahl's method is not applicable for compounds containing nitrogen in nitro and azo groups and nitrogen present in the ring. Because nitrogen of these compounds does not change to ammonium sulphate under these conditions.
Hence only Alanine can be used to determine percentage of nitrogen.
