Solution

The correct options are
B Glucose + Glucose
D Glucose + Maltose
The tertiary structure of a protein is the way a polypeptide folds itself to form a functional protein or forming a subunit of a functional protein. The tertiary structure of a protein is stabilised by ionic interactions, hydrogen bonds, vanderwaals interactions and disulphide bridges.

Therefore the answer here is ionic interactions and disulphide bridges. They are not stabilised by hydrogen bonds alone and peptide bonds form the primary structure of the protein, the linkage between amino acids forming the polypeptide chain.
