Answer 1

The most commonly recognized factor among the options provided that is a cause of cancer is **use of tobacco**. Tobacco use is a well-established risk factor for several types of cancer, including lung, mouth, throat, and many others. While high stress levels, exposure to viruses, and autoimmune disorders can be associated with cancer in certain contexts, they are not as universally acknowledged as direct causes of cancer as tobacco use is.
