The interactions that stabilize secondary, tertiary, or quaternary structures during protein folding are:

1. Hydrogen bonds: These are crucial for the formation of secondary structures like alpha-helices and beta-sheets. They also play a role in the stabilization of tertiary and quaternary structures.

2. Ionic bonds: These are important in the stabilization of tertiary and quaternary structures. They occur between the side chains of amino acids that carry a charge.

3. Van der Waals forces: These weak interactions also contribute to the stabilization of tertiary and quaternary structures. They occur between the atoms of nonpolar side chains.

4. Peptide bonds: These bonds link amino acids together to form the primary structure of a protein. They do not play a direct role in the stabilization of secondary, tertiary, or quaternary structures.

So, the correct answer is C. I, II, and III only.
