### Core Concept
Serum sickness is a type of immune complex-mediated hypersensitivity reaction that occurs in response to the administration of foreign proteins, such as antivenom or immunoglobulin. This condition is characterized by the formation of antigen-antibody complexes that deposit in various tissues, leading to an inflammatory response.

### Why the Correct Answer is Right
The correct answer is not provided in your question, but I can still explain the mechanism behind serum sickness. Serum sickness involves the activation of the complement system and the recruitment of neutrophils and macrophages to the site of antigen-antibody complex deposition. This leads to the release of various inflammatory mediators, including histamine, bradykinin, and prostaglandins, which cause symptoms such as fever, rash, and joint pain. The condition can also lead to more severe complications, such as glomerulonephritis and vasculitis.
