Sensitization in transplant candidates occurs due to the immune system's exposure to foreign antigens, which leads to the production of antibodies that can complicate transplantation. The correct option identifies pregnancy, blood transfusions, and previous transplants as key factors that can lead to sensitization.

During pregnancy, the exposure of the maternal immune system to paternal antigens from the fetus can result in the mother developing antibodies against those antigens. This can result in sensitization that affects future transplant opportunities. Blood transfusions also introduce foreign antigens into the recipient's body, particularly if the blood type is incompatible, triggering an immune response and the formation of antibodies. Similarly, previous transplants expose the immune system to unfamiliar antigens, leading to sensitization that can impact compatibility with subsequent transplants.

Understanding these mechanisms is crucial for healthcare providers in managing transplant candidates, as sensitization can increase the risk of transplant rejection and can limit the donor pool.
