Answer 1

The answer is primary. That means the answer is a.

Hope this helped☺☺

Answer 2

Tertiary

The secondary structure begins the folding up process where as in the tertiary structure, the protein is folded into its accurate 3D structure, associating to the purpose. This is tied together by a series of non-covalent communications between side groups, including ionic communications, disulphide bonds, hydrophobic interactions, Van der Waals energies and hydrogen bonds.
