C Correct answer
Explanation

In influenza viruses like H1N1, the H refers to hemagglutinin, a surface glycoprotein that helps the virus bind to host cells. The N refers to neuraminidase. Haemoglobin carries oxygen in blood (not viral). Hongkong is a place. Hemoprotein is a general term for iron-containing proteins, not the specific viral protein.
