What is false of the following statements about the clonal-selection theory of immune system function?

The clonal-selection theory posits that each lymphocyte expresses a specific receptor for a particular antigen, and upon encountering its specific antigen, it proliferates and differentiates into effector cells. A false statement about this theory might be that all lymphocytes can recognize and respond to any antigen, as the theory emphasizes that only those with the matching receptor are activated. Furthermore, it does not suggest that immune memory is formed solely from the initial response, as memory cells are also generated during the clonal selection process for future encounters with the same antigen.
