CD20 is expressed on which cells?

Explanation:
CD20 is a marker found on mature B lymphocytes, from pre-B cells through memory B cells, and it is not expressed on T lymphocytes, red blood cells, or platelets. This makes B lymphocytes the cells that carry CD20. In clinical practice, this marker is targeted by anti-CD20 therapies (like rituximab) to deplete B cells. That's why the correct choice is the B lymphocytes.
