Solution

The correct option is C Low pressure
The veins carry deoxygenated blood from the tissues back to the heart. Veins carry blood at low pressure from tissues to the heart. This flow of blood at low pressure increases the possibility of the blood flowing in backward direction. Thus, valves are present in the veins to prevent backflow of blood at low pressure.
