Answer
This option is incorrect because hydrogen bonds primarily play a role in the secondary structure (e.g., alpha helices and beta sheets) and are also important in tertiary and quaternary structures, but not necessarily during the formation of these structures.
Step 2
B. primary, secondary and tertiary structures only.

Answer
This option is correct. Hydrogen bonding is crucial in the formation of secondary structures and continues to stabilize tertiary structures. However, primary structure is determined by covalent peptide bonds, not hydrogen bonds.
Step 3
C. tertiary and quaternary structures only.

Answer
This option is incorrect because while hydrogen bonding is important in tertiary and quaternary structures, it also plays a significant role in establishing secondary structures.

Answer
This option is incorrect. The primary structure is formed by peptide bonds and does not involve hydrogen bonding, which is important for the secondary and tertiary structures.
