Answer:
A
Explanation:
The absolute period refers to the period when the entire heart is in diastole, i.e., the relaxation phase, and there is no contraction. During this phase, the heart is filling up with blood from the atria, and there is no ejection of blood into the ventricles. The duration of this period is around 0.2 seconds. After this, the atria contract, and the ventricles start to fill, leading to the ventricular systole or the contraction phase. Thus, option A is the correct answer.
