It creates a variety of immune responses in the host organisms.

Answer 1

It makes them unrecognizable to the immune system.

Explanation: Antigenic drift are small mutations in the genes for viral surface proteins, changing antigen structure so existing host antibodies are less effective, allowing immune evasion.
