Final answer:
The procedure that uses liquid nitrogen to destroy abnormal tissue is known as cryosurgery. It is a medical technique where extreme cold is applied to eliminate diseased or unwanted tissue, such as warts and some tumors.
Step-by-step explanation:
The procedure that uses liquid nitrogen to destroy abnormal tissue, such as warts, tumors, or infected tissue is called cryosurgery. This method involves applying extreme cold to targeted tissue, leading to its destruction. Cryosurgery is commonly used for the removal of warts but is also effective for a variety of other medical issues, including some types of cancer. Other procedures such as electrosurgery and laser surgery are used for different medical applications and have distinct methodologies. For example, electrosurgery burns the tissue with electric currents, while laser surgery cuts or burns the tissue with a highly focused beam of light. Chemotherapy involves the use of drugs to treat diseases like cancer and is not related to the freezing of tissues. Therefore, the correct answer to the question is A) Cryosurgery.
