Solution

The correct option is C Formylated methionine
The first amino acid in any polypeptide chain of a prokaryote is always formylated methionine. The first amino acid is methionine in eukaryotes. This is because AUG is a start codon that codes for formylated methionine in prokaryotes and methionine in eukaryotes.
Thus, the correct answer is 'Formylated methionine.'
