Blood vessels which carry blood from different organs of the body to the heart

The correct option is B Veins

• These are blood vessels that take blood back to the heart, this blood contains less oxygen and is rich in waste products that are to be excreted or removed from the body. Veins become larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.

So, the correct option is 'Veins'.
