उत्तर
A is false but R is true.
Explanation:
The assertion is false because arteries lack internal valves. Arteries do not require valves because the heart pumps blood out under extremely high pressure, ensuring it travels rapidly in a single, unidirectional path with zero risk of backflow. However, the reason is entirely true because it accurately details the anatomical rule of circulation: all systemic arteries carry oxygen-rich blood away from the heart to sustain body tissues, with the unique exception of the pulmonary artery, which routes oxygen-depleted blood to the lungs.
