The chamber of the heart that receives blood from the pulmonary veins is the C. left atrium. The atrium of the heart is a chamber that serves for collecting blood. Thus, choices A and D are incorrect. Now, left atrium collects oxygenated blood and right atrium collects deoxygenated blood. Since the pulmonary veins carry oxygenated blood, the blood from the pulmonary veins will be collected in the left atrium.
