Answer 1

The Weil-Felix test is the serological test used for the diagnosis of Q-fever. It detects antibodies produced in response to the Coxiella burnetii bacteria. Hence the correct answer is option C

Step-by-step explanation:

The serological test used for the diagnosis of Q-fever is the Weil-Felix test. This test detects antibodies produced by the body in response to the Coxiella burnetii bacteria, which causes Q-fever. The Weil-Felix test is based on the principle of agglutination, where the patient's serum is mixed with specific antigens derived from Proteus bacteria, and if the antibodies are present, agglutination will occur.

Hence the correct answer is option C
