B Systole (contraction) and diastole (relaxation)

C Atrial contraction and ventricular relaxation only
D Depolarization and repolarization
Correct Answer

Option B is the correct answer.

Detailed Explanation

The cardiac cycle consists of systole (contraction of the heart muscle) and diastole (relaxation of the heart muscle). These alternating phases allow the heart to pump blood efficiently while refilling between beats.

Hint

One phase involves contraction and pumping; the other involves relaxation and filling.
