Once in the respiratory tract, the flu virus targets cells based on specific glycoproteins on their surfaces. How does the virus gain entry into the target cell?

Question

A. Viruses are made up of lipids and can therefore diffuse through the membrane of target cells, gaining entry.
B. Glycoproteins within the virus structure bind with glycoproteins on the membrane of the target cell and the virus squeezes through the glycoprotein into the cell.
C. The H spikes of the influenza virus break down the cell wall, allowing the virus to gain entry.
D. The N spikes of the influenza virus help break down the plasma membrane of a cell, allowing entry of the virus into the cell.
