Explanation:

When the immune system is activated by a foreign body (like a pathogen), it can cause symptoms such as coughing, sneezing, and fever. These are part of the body's defense mechanism. Option A (symptoms from being over - worked and tired) is not related to the immune response. Option B (immune system failing) would likely lead to more severe and persistent health issues rather than these typical immune - response symptoms. Option C (psychological response) is incorrect as these are physical immune - related symptoms. Option D correctly states that the symptoms are a direct indication of the immune system being activated by a foreign body.

Answer:

D. Sonja's symptoms are a direct indication that her immune system has been activated by a foreign body and it is fighting to get rid of the intruder.
