Verified By Collegedunia
The Correct Option is C
Solution and Explanation
In pathology, necrosis is a form of cell injury that results in the premature death of cells in living tissues. Necrosis due to immune reactions in blood vessels is typically characterized by a type known as fibrinoid necrosis.
Fibrinoid necrosis occurs when the immune system targets blood vessels, leading to the deposition of immune complexes and fibrin, creating a bright pink appearance histologically due to the accumulation of eosinophilic material, which resembles fibrin. This is often associated with conditions related to immune-mediated vascular injury, such as vasculitis or in hyperacute transplant rejection.
Therefore, the correct type of necrosis seen in blood vessels due to immune reactions is fibrinoid necrosis.
