There is oozing of semisolid material which forms a tough membrane over air passage .The disease is

Options

A. whooping cough
B. diphtheria
C. pulmonary tuberculosis
D. measles

Answer

**Step-by-Step Solution:**

1. **Understand the Symptoms Described**: The question describes a condition characterized by the oozing of semi-solid material that forms a tough membrane over the air passage. This suggests a respiratory disease that leads to the formation of a membrane.

2. **Evaluate the Options**:
- **Option A: Whooping Cough (Pertussis)**: Caused by Bordetella pertussis, this disease is characterized by severe coughing fits but does not form a membrane over the air passage. Symptoms include runny nose and sneezing. Therefore, this option is incorrect.

- **Option B: Diphtheria**: Caused by Corynebacterium diphtheriae, diphtheria is known for forming a pseudomembrane in the throat and nasal passages. This membrane can be tough and may appear greenish, bluish, or blackish. It is a highly contagious respiratory disease, and the symptoms include low-grade fever, malaise, weakness, and a characteristic "bull neck" appearance due to swollen lymph nodes. This option fits the description given in the question, making it a likely correct answer.

- **Option C: Pulmonary Tuberculosis**: Caused by Mycobacterium tuberculosis, this disease primarily affects the lungs and is characterized by symptoms such as cough, weight loss, and night sweats. It does not form a membrane over the air passage, so this option is incorrect.

- **Option D: Measles**: Caused by the Paramyxovirus, measles is a viral infection that affects the respiratory tract but does not cause the formation of a membrane over the air passage. Therefore, this option is also incorrect.

3. **Conclusion**: After evaluating all the options, the disease that matches the description of oozing semi-solid material and forming a tough membrane over the air passage is **Diphtheria**.

**Final Answer**: The disease is Diphtheria.
