Identify the statement that does not provide accurate evidence as to why HIV is so lethal.
a.
During the course of infection, HIV increases immune activation by altering intestinal physiology to let more microbes into the blood supply.
b.
Immune evasion increases in many infections due to HIV virions evolving new and unrecognizable epitopes (antigens).
c.
In many individuals the virus population evolves to use different receptors to gain access to a greater diversity of host immune cells.
d.
HIV causes enhanced replication and proliferation of T cells, which allows the immune system to work better at defending against pathogens.
