Match List-I with List-II.
| List-I (Disease) | List-II (Feature) |
| A. Typhoid | I. Infects the nose and respiratory passage but not the lungs |
| B. Pneumonia | II. Sustained high fever |
| C. Common cold | III. Chronic inflammation of the lymphatic vessels of the lower limbs |
| D. Filariasis | IV. Alveoli get filled with fluid |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-II, B-IV, C-I, D-III
(A) Typhoid — this matches (II) Sustained high fever. Salmonella typhi enters through contaminated food and water. The main symptom is a sustained high fever of 39° to 40°C, with weakness, stomach pain and loss of appetite.
(B) Pneumonia — this matches (IV) Alveoli get filled with fluid. Streptococcus pneumoniae and Haemophilus influenzae infect the alveoli of the lungs. The fluid in the alveoli causes severe problems in respiration.
(C) Common cold — this matches (I) Infects the nose and respiratory passage but not the lungs. Rhino viruses cause the common cold. The lungs are not affected, which sets it apart from pneumonia.
(D) Filariasis — this matches (III) Chronic inflammation of the lymphatic vessels of the lower limbs. The filarial worms, Wuchereria, live in these vessels for many years, and the disease is also called elephantiasis.
