Solution
The correct option is
A
HIV does not escape but attacks the acquire immunity response
Vaccines typically work by triggering the immune system to produce antibodies that help to beat infections.
But most antibodies can't secure and neutralize HIV.
The proteins on the surface of the virus mutate rapidly and change shape continuously.
Hence, HIV does not escape but attacks the acquire immunity response is correct regarding AIDS causative HIV.
So, the correct answer is 'HIV does not escape but attacks the acquire immunity response'.
