The correct answer is (b). Oral submucous fibrosis (OSMF) is a chronic inflammatory condition of the oral mucosa that is associated with the use of smokeless tobacco. It is characterized by progressive fibrosis of the submucosa, which can lead to trismus (inability to open the mouth), difficulty swallowing, and tooth loss.

(a) Drinking liquor is not a known cause of OSMF.
(c) Consuming gutka of tobacco is a form of smokeless tobacco and is a known cause of OSMF.
(d) Consuming red meat is not a known cause of OSMF.

OSMF is a serious condition that can have a significant impact on quality of life. There is no cure for OSMF, but treatment can help to manage the symptoms and slow the progression of the disease. Treatment options include surgery, medication, and lifestyle changes.
