The correct answer is: If both assertion and reason are true but reason is not the correct explanation of assertion.
In $\beta$-pleated sheet structure, the polypeptide chains are held together by intermolecular $H$-bonds. Extension and contraction of $\beta$-pleated sheet structure of protein depends on the size of $R$.
