A
To lower the temperature of the body to kill the bacteria
B
The increase the temperature of the body to kill the bacteria
C
To allow the bacteria to take over
D
To make you feel miserable
Explanation: 

Detailed explanation-1: -Most bacteria and viruses that cause infections in people thrive best at 98.6°F (37°C). Many infants and children develop high fevers with mild viral illnesses. Although a fever signals that a battle might be going on in the body, the fever is fighting for, not against the person.

Detailed explanation-2: -Fever results in an increase in the destruction of the invading bacteria by increasing the effectiveness of body defenses and an inhibiting bacterial metabolism.

Detailed explanation-3: -As ambient temperatures increase, homeotherms use evaporative cooling through sweating and/or panting to regulate body temperatures, and also vasodilate surface blood vessels to promote heat loss (Robertshaw 2006).

Detailed explanation-4: -When the environment is not thermoneutral, the body uses four mechanisms of heat exchange to maintain homeostasis: conduction, convection, radiation, and evaporation.
