Which of the following statements are true concerning how an influenza virus identifies and infects its target cells?

The right answer is B. Hemagglutinin

Explanation:

Hemagglutinins are triangular rods. They allow the attachment of Influenza viruses on the target cells of the respiratory tree. In the presence of red blood cells, a haemagglutination (liquid medium) is obtained.

About the other components of Influenza virus:Neuraminidase is a mushroom-shaped spike composed of a tetramer consisting of 4 subunits of a single glycoprotein. At 37 ° C, the neuraminidase destroys the bonds (virus - cells) and thus allows the release of neoformed virions in the external environment: it is elution.

The membrane protein M and the protein subunits of the nucleocapsid are antigenic and are the basis of the classification of Influenza virus types A, B and C. They induce the synthesis of non-protective antibodies fixing the
