Solution

The correct option is A Ser and Thr
Attachment of oxygen of sugar molecule to the amino residue is called O-linked glycoprotein. In O-linked glycoprotein carbohydrate covalent attachments to protein involve a linkage between the monosaccharide N-Acetylgalactosamine and amino acids serine and threonine.
So, the correct option is 'Ser and Thr'.
