According to the clonal selection theory, an antigen
- A. creates antibodies from scratch
- B. converts T cells into B cells
- C. selects and stimulates the lymphocyte clone bearing the matching receptor
- D. suppresses every lymphocyte equally
Explanation
The body already holds millions of lymphocyte clones, each with one receptor; the antigen simply picks the matching one and drives its expansion. Selection, not instruction, is the theory's key word.
