Step 1: Define each condition in List-I✦ Active

Let's define each medical condition listed in List-I: * **Emphysema:** A chronic lung disease characterized by damage to the alveolar walls, leading to a decrease in the respiratory surface area. * **Angina Pectoris:** Acute chest pain that occurs when the heart muscle does not receive enough oxygen-rich blood. * **Glomerulonephritis:** Inflammation of the glomeruli (tiny filtering units) in the kidneys. * **Tetany:** A condition characterized by involuntary muscle contractions (spasms) due to an imbalance of electrolytes, particularly low calcium levels (Ca++) in the blood.

Step 2: Match List-I items with their descriptions in List-II○ Expand

Based on the definitions: * A. Emphysema matches II. Damaged alveolar walls and decreased respiratory surface. * B. Angina Pectoris matches III. Acute chest pain when not enough oxygen is reaching to heart muscle. * C. Glomerulonephritis matches IV. Inflammation of glomeruli of kidney. * D. Tetany matches I. Rapid spasms in muscle due to low Ca++ in body fluid.

💡 Teacher's Secret Hint

Remember that Emphysema is a respiratory disorder, Angina Pectoris is a cardiac issue, Glomerulonephritis is renal, and Tetany is related to calcium metabolism and muscle function.

Step 3: Select the correct option○ Expand

The correct combination is A-II, B-III, C-IV, D-I. Comparing this with the given options: * Option (1): A-III, B-I, C-IV, D-II (Incorrect) * Option (2): A-III, B-I, C-II, D-IV (Incorrect) * Option (3): A-II, B-IV, C-III, D-I (Incorrect) * Option (4): A-II, B-III, C-IV, D-I (Correct) Therefore, option (4) is the correct answer.
