During protein synthesis in cells, amino acids condense (in the presence of enzymes) through the formation of the amide link `(–CONH–)`, or peptide bond, to form a polypeptide chain, which then folds to form a biologically active protein.
The equation below shows the formation of a dipeptide, Ala-Gly, formed by condensation of the two amino acids, alanine and glycine in a test tube.

Which of the following statements is/are true for the above reaction?
(i) A dipeptide Gly-Ala is equally likely to be formed by condensation of alanine and glycine.
(ii) Water is eliminated in the above condensation reaction.
(iii) Oxygen and hydrogen is released as gases in the above condensation reaction.

Options

A. i only
B. i and ii only
C. ii and iii only
D. all- i,ii, and iii
