Explanation:

Question 5

Lysozyme is an enzyme with antibacterial properties. It is known to be present in tears (to protect the eye) and saliva (to help in oral defense). Tears and saliva are the correct sources.

Cell markers (like cell surface markers) can be composed of proteins (e.g., glycoproteins), lipids (e.g., glycolipids), and sugars (as part of glycoproteins/glycolipids). Starch is a storage polysaccharide in plants and not a component of cell markers. So protein, lipids, and sugars are correct.

Answer:

C. tears and saliva
