Solution
The correct option is B Lung cancer
Smoking and exposure to certain chemicals can greatly increase risk of getting lung cancer. Lung cancer is caused by a mutation in DNA. When cells reproduce, they divide and replicate, forming identical cells, so that body is constantly renewing itself. Inhaling harmful, cancer-causing substances (carcinogens) like cigarette smoke, asbestos, and radon, damages the cells that line our lungs. At first body may be able to repair itself. With repeated exposure cells become increasingly damaged. Over time, the cells begin to act abnormally and grow uncontrollably. This is how cancer can develop.Therefore, the correct answer is option B.
