A)destroys T cells that do not recognize self-molecules of MHC.
B)destroys B cells that make antibodies against self.
C)destroys MHC molecules.
D)destroys CD4⁺ cells that attack self.
E)activates B cells.

Question

Quizplus · Accepted Answer

Thymic selection is the process in which T cells that recognize self-molecules of MHC survive and mature, whereas T cells that do not recognize self-molecules are destroyed. Therefore, option A is the correct answer. Option B is incorrect because thymic selection only applies to T cells, not B cells. Option C is incorrect because thymic selection does not destroy MHC molecules. Option D is incorrect because CD4⁺ cells are not attacked during thymic selection, but rather selected based on their ability to recognize self-MHC molecules. Option E is incorrect because thymic selection does not activate B cells, but rather selects T cells.
