d. symptoms of infection indicate that the body is unprepared to combat invading microorganism

B

Explanation:

Symptoms of infection indicate that the body is trying to combat invading microorganisms. Fever for example is a very common symptom with which the body is defending itself against external organisms. The body uses fever as a great weapon because when the body raises up temperature, many of the organisms causing infectionwill tend to be destroyed. For this reason, fever should not be abolished with medicine. It should be maintained in a point were the foreign organisms are killed and the body is protected.

The symptoms such as head ache, fever, tiredness and several other, should be respected, monitored and if it is the case, treated with medicine in case the "battle" of the invasors against the body are winning the battle.
