The correct answer is: 6

Peptide linkage is also known as peptide bond. It is an amide formed between COOH and NH2 group by elimination of a water molecule. It is represented as
-CO-NH-.

Number of peptide linkages =(Total amino acids -1)

Now, given that short peptide on hydrolysis give seven amino acids.
=7-1=6
