Emphysema is a form of chronic lung disease, usually caused by smoking.
Bronchitis is caused by tobacco smoke, dust, fumes, vapors and air pollution.
Gastric and duodenal ulcers that occur in the stomach are called as gastric ulcers. Ulcers that occur in the upper area of small intestine, which is the duodenal ulcers.
Therefore, the correct answer is option D.

Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). It is mainly caused because of Smoking. Shortness of breath is the most common symptom of emphysema. A cough, sometimes caused by the production of mucus, and wheezing may also be symptoms of emphysema. Stopping of smoking and bronchodilating medications along with steroid medications are the treatment of this disease. Hence, the correct answer is option C.

Therefore, the correct answer is option B.

Prolonged smoking tends to stain the teeth and change its color, tooth decays and gum diseases.

• The leading causes of mouth cancer are tobacco and alcohol. The next major cause is cigarette smoking.
  
• Both are carcinogenic, which means they contain chemicals that can damage the DNA in cells and lead to cancer
  

Smog contains pollutants like ozone, nitrogen oxides, and particulate matter, which are primarily respiratory irritants that damage the lungs.

Cigarette smoking causes lung cancer by damaging the cells that line the lungs. When we inhale cigarette smoke, which is full of cancer-causing substances (carcinogens), changes in the lung tissue begin almost immediately. At first our body may be able to repair this damage. But with each repeated exposure, normal cells that line our lungs are increasingly damaged. Over time, the damage causes cells to act abnormally and eventually cancer may develop. People who smoke cigarettes are 15 to 30 times more likely to get lung cancer or die from lung cancer than people who do not smoke. Even smoking a few cigarettes a day or smoking occasionally increases the risk of lung cancer. The more years a person smokes and the more cigarettes smoked each day, the more risk goes up. Cigarette smoking causes many types of cancer, including cancers of the lung, oesophagus, larynx (voice box), mouth, throat, kidney, bladder, pancreas, stomach, and cervix, as well as acute myeloid leukemia.
