Lymphocytes select one:

a. possess mhc antigens for recognizing self.
b. have membrane receptors that recognize foreign antigens.
c. gain tolerance to self by destruction of lymphocytes that could react against self.
d. develop into clones of b and t cells with extreme variations of specificity.
e. all of the choices are correct.

The correct option is E.

Explanation:

Lymphocytes are known as white blood cells, and also main type of immune cells. They are synthesized in the bone marrow, and present in the blood, and lymph tissues.

1) The immune cells work together to protect the body against foreign molecules such as virus, and bacteria.

2) They contain MHC antigens for recognizing self.

3) They contain membrane receptors that recognize foreign antigens.

4) They are helping to develop into clones of B and T cells with extreme variations of specificity.
