A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-iii, d-i
D

Correct Answer
Option A
Detailed Explanation
The P-wave represents the electrical excitation of the atria leading to their contraction, while the QRS complex indicates the depolarisation of the ventricles. The T-wave corresponds to the repolarisation of the ventricles, and cardiac output refers to the volume of blood pumped by the heart per minute.
