May be the answer is : d.. bcz of salt bridge made of by the hydrogen bond and we knw H- bonding highly stable...for that reason last one is the answer...what is the answer???

I think the answer would be-
© increase in water of hydration.....
Because due to same CD value (a) is impossible......
As both are equally susceptible to hydrolysis in the presence or absence of reducing agent, the disulfide bonds are same for both.....So (b) is excluded....
As amino acid composition is 95% similar, there will be almost same number of amino acids with positively and negatively ​charged amino acids contributing same number of salt bridges...So option (d) is not possible....


Rest is option ©.....


Is my logic correct or not.....Please let me know......
Thank you....
