Answer:
B) 3 amino acids joined by 2 peptide bonds
Step-by-step explanation:
The general formula of amino acids:
R-CH(NH2)-COOH
It can be seen clearly in the attached image that there are three amino acid molecules.
Now the three molecules of amino acids are joined by 2 peptide bonds.
Peptide bond: a bond formed between first carbon of one amino acid and nitrogen of another amino acid releasing a water molecule( H2O).
