The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.

Explanation:

Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.

Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.

well the answer is 2!
