The answer is B) Phosphorus-32.

Explanation for each option:

A) Xenon-133: This radioisotope is primarily used in the field of nuclear medicine for lung ventilation studies. It is not typically used for treating leukemia and lymphomas.

B) Phosphorus-32: This radioisotope is used in the treatment of certain types of leukemia and lymphomas. It is a beta-emitting radioisotope that can be used to target and destroy cancerous cells in these conditions.

C) Iridium-192: This radioisotope is commonly used in brachytherapy, a form of internal radiotherapy, for treating various types of cancer, but it is not specifically used for leukemia and lymphomas.

D) Thallium-201: This radioisotope is used in medical imaging, particularly in stress tests for the heart, and is not used for treating leukemia and lymphomas.

In summary, Phosphorus-32 is the correct radioisotope used for treating leukemia and lymphomas.
