Which of the following blood vessels contains valve?

The answer is B : VEINS

Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.

There are three types of veins which are :

• Deep veins are located within muscle tissue. 
• Superficial veins are closer to the skin's surface.
• Pulmonary veins transport blood that's been filled with oxygen by the lungs to the heart.
