Solution

The correct option is B Deoxygenated blood
During joint diastole, when both the auricles and the ventricles relax simultaneously the atria receive blood from the great veins and the coronary sinus. Since blood is received by the auricles from the veins it is deoxygenated blood. So, the correct option is 'deoxygenated blood'.
