Match List-I with List-II.

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

Choose the correct answer from the options given below:

The correct answer is A-II, B-III, C-IV, D-I.

Let us look at the detailed explanation for each matching pair:

A. Emphysema matches with II (Damaged alveolar walls and decreased respiratory surface):
Emphysema is a chronic respiratory disorder where the walls of the alveoli (air sacs in the lungs) are damaged. This damage leads to the breakdown of the alveolar walls, reducing the effective surface area available for gas exchange. Cigarette smoking is one of the major causes of this condition.

B. Angina Pectoris matches with III (Acute chest pain when not enough oxygen is reaching to heart muscle):
Angina Pectoris, commonly known as angina, manifests as acute chest pain or discomfort. It occurs when the coronary arteries cannot supply sufficient oxygen-rich blood to the heart muscle (myocardial ischemia), particularly during physical exertion or stress.

C. Glomerulonephritis matches with IV (Inflammation of glomeruli of kidney):
The suffix "-itis" indicates inflammation. Glomerulonephritis refers to the inflammation of the glomeruli, which are the tiny filtering units of the kidneys. This condition affects the kidney's ability to filter waste and excess fluids from the blood.

D. Tetany matches with I (Rapid spasms in muscle due to low Ca⁺⁺ in body fluid):
Tetany is a medical condition characterized by rapid spasms and wild contractions of the muscles. It is caused by low calcium (Ca⁺⁺) levels in the body fluids, which increases the excitability of peripheral nerves and leads to involuntary muscle activity.

Combining all the correct matches, we get:
A - II, B - III, C - IV, D - I
