Q. Cornea transplant in humans is almost never rejected. This is because
A) It is a non-living layer
B) Its cells are least penetrable by bacteria
C) It has no blood supply
D) It is composed of enucleated cells
Explanation
[Solution from source] The cornea is avascular, so immune cells and antibodies carried in the blood rarely reach the graft and rejection seldom occurs. The cornea is living tissue with nucleated cells, so the 'non-living' and 'enucleated' options are false. Answer (3).
