Solution

The correct option is D Diphtheria, leprosy, plague
Diphtheria is a serious bacterial infection that affects the mucous membranes of the throat and nose. Although it spreads easily from one person to another, diphtheria can be prevented through the use of vaccines. A type of bacteria called Corynebacterium diphtheriae causes diphtheria. The condition is typically spread through person-to-person contact or through contact with objects that have the bacteria on them, such as a cup or used tissue. Even if an infected person doesn’t show any signs or symptoms of diphtheria, they’re still able to transmit the bacterial infection for up to six weeks after the initial infection. diphtheria is still fairly common in developing countries where immunization rates are low.
Leprosy is a chronic, progressive bacterial infection caused by the bacterium Mycobacterium leprae. It primarily affects the nerves of the extremities, the skin, the lining of the nose, and the upper respiratory tract. Leprosy is also known as Hansen’s disease. Leprosy produces skin ulcers, nerve damage, and muscle weakness. If it isn’t treated, it can cause severe disfigurement and significant disability. Leprosy is one of the oldest diseases in recorded history. The first known written reference to leprosy is from around 600 B.C. Leprosy is common in many countries, especially those with tropical or subtropical climates.
The plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually transmitted to humans through fleas. The risk of plague is highest in areas that have poor sanitation, overcrowding, and a large population of rodents. In medieval times, the plague was responsible for the deaths of millions of people in Europe. Today, there are only 1,000 to 2,000 cases reported worldwide each year, with the highest incidence in Africa. Plague is a rapidly progressing disease that can lead to death if untreated.
So the correct option is 'Diphtheria, leprosy, plague'.
