Match List-I with List-II.

	List-I		List-II
A.	Emphysema	I.	Rapid spasms in muscle due to low Ca²⁺ in body fluid
B.	Angina Pectoris	II.	Damaged alveolar walls and decreased respiratory surface
C.	Glomerulonephritis	III.	Acute chest pain when not enough oxygen is reaching to heart muscle
D.	Tetany	IV.	Inflammation of glomeruli of kidney

Choose the correct answer from the options given below :

We examine each condition in List‑I and identify the matching description in List‑II.

• Emphysema is a disease in which the alveolar walls are destroyed, reducing the respiratory surface. This corresponds to description II: “Damaged alveolar walls and decreased respiratory surface”.

• Angina pectoris causes sudden chest pain because the heart muscle does not receive enough oxygen. This matches description III: “Acute chest pain when not enough oxygen is reaching to heart muscle”.

• Glomerulonephritis is an inflammation of the kidney’s glomeruli. Therefore it aligns with description IV: “Inflammation of glomeruli of kidney”.

• Tetany manifests as rapid muscle spasms due to low calcium (Ca²⁺) in body fluids. This fits description I: “Rapid spasms in muscle due to low Ca²⁺ in body fluid”.

Combining the matches gives the final pairing:

A → II,  B → III,  C → IV,  D → I.
