The common symptoms of the flu include fever, cough, and body aches, as these are characteristic indicators of a viral infection affecting the respiratory system. The flu is caused by influenza viruses, which lead to systemic symptoms due to the body's immune response to the infection. The fever indicates an immune response, the cough reflects respiratory involvement, and body aches are often a result of the body's overall reaction to fight off the virus.

In comparison, the other options list symptoms that are typically associated with different medical conditions. Chest pain and difficulty breathing might indicate a heart or significant respiratory issue, which are not primary symptoms of the flu. Rash and swelling in the joints are more common in allergic reactions or arthritic conditions. Lastly, while headaches and nausea can sometimes accompany the flu, they are not primary indicators and could be associated with a variety of other illnesses. Thus, the combination of fever, cough, and body aches uniquely aligns with the common presentation of the flu.
