Complete answer:
In order to answer this question we should have knowledge about disease and its classification:
Disease: It is the abnormal condition of certain organs of the body due to many underlying medical conditions and complications. Diseases may be classified as infectious diseases, deficiency diseases, hereditary diseases and physiological diseases. Diseases can also be classified into communicable and non-communicable diseases.
Disease is an abnormal condition that causes disruption in the functions or structure of all or part of an organism’s body. Diseases are associated with specific symptoms. It may be caused by pathogens or by internal dysfunctions of the immune system such as immunodeficiency, hypersensitivity, allergies and autoimmune disorders.
The diseases which spread from person to person or from animal to person are called Communicable diseases. This transfer happens through air, contact with contaminated surfaces, or direct contact with blood, feces, or other bodily fluids. Examples: Influenza, athlete's foot etc.
Non-communicable diseases: Medical conditions that are not infectious and cannot be passed from one person or animal to another. Another name for this is chronic diseases. These diseases tend to be of long duration and are the result of combined effects of genetic, physiological, environmental factors. Examples: Cancer, cardiovascular diseases etc.
Diseases such as influenza, tuberculosis, dysentery, chickenpox are infectious. Infectious diseases can be transmitted, by hand-to-mouth contact with infectious surfaces, by bites of insects or other carriers, and from contaminated water and food, etc. Heart diseases, and mental disorders are non-infectious diseases.
Ulcers are sore that develop on the lining of the esophagus, stomach, intestines, and digestive tract thus damaging them. Common causes include the bacteria H. Pylori and anti-inflammatory pain relievers including aspirin. Upper abdominal pain is a common symptom. Medication is required to decrease stomach acid production. If it is caused by bacteria, antibiotics may be required. They are not contagious.
Tuberculosis is a serious infectious bacterial disease that affects the lungs. It spreads when an infected person coughs or sneezes. The symptoms seen include cough, weight loss, night sweats and fever. Multiple antibiotics are used for long durations while treating the patient.
Dysentery is Inflammation of the intestines accompanied by bloody diarrhoea. It is by shigella bacteria or an amoeba. Dysentery spreads through contaminated food and water. A key symptom is bloody diarrhoea. Abdominal cramps, fever and malaise are few other common symptoms. Prompt medical care is required for bloody diarrhoea. Increased fluid intake, rehydration solutions, IV fluids and antibiotics are included in treating it.
Chickenpox is a highly contagious viral infection. Its treatment involves relieving symptoms or antiviral medication in serious cases. It is preventable by vaccine but spreads easily. Symptoms commonly observed are itchy, blister-like rashes on skin.

Therefore, the correct answer is option d, ulcer.

Note: The study of disease is termed as pathology, which also includes the study of its causes known as etiology.
In humans, coronary artery disease is the deadliest one, followed by cerebrovascular disease and lower respiratory infections. In many countries, neuropsychiatric conditions, such as depression and anxiety cause most sickness overall.
