Several genes coding for enzymes associated with osmotic adjustment are turned on (up-regulated) by osmotic stress and/or salinity, and cold stress. These genes encode enzymes such as the following;

I) ∆′1-Pyrroline-5-carboxylate synthase, a key enzyme in the proline biosynthetic pathway

II) myo-Inositol 6-O-methyltransferase, a rate-limiting enzyme in the accumulation of the cyclic sugar alcohol called pinitol

III) Betaine aldehyde dehydrogenase, an enzyme involved in glycine betaine accumulation

Given following statements of gene encoding enzyme is correct?

Which of the following is incorrect 

a) antiparallel β sheets are frequently found and they are quite more stable because of more no. hydrogen bond presence and linear H bonding pattern.

b) antiparallel β sheets are frequently found and they are quite more stable because of more no. hydrogen bond presence and having distorted H bonding pattern.

c) parallel β sheets are relatively less stable and mostly found in core of protein.
