(a) Statement (i) is correct while statement (ii) is incorrect.
(b) Statement (ii) is correct while statement (i) is incorrect.
(c) Both statements are correct.
(d) Both statements are incorrect.

Correct Answer: (b) Statement (ii) is correct while statement (i) is incorrect.

Explanation:

Arteries have thicker muscular walls than veins because arteries have to pump the blood with higher pressure to make it reach different parts of the body.

Arteries	Veins
Arteries carries oxygenated blood away from the heart.	Vein transports de-oxygenated blood towards the heart.
Pulmonary arteries are the only arteries that carries de-oxygenated blood.	Pulmonary veins are the only veins that carry oxygenated blood.
Oxygen level is high and carbon dioxide level is low in arterial blood.	Oxygen level is low and carbon dioxide level is high in arterial blood.
Arteries are usually positioned deeper inside the body.	Veins are usually positioned closer or beneath the skin surface.
Walls of the arteries are much stronger and rigid compare to veins	Walls of the veins are less strong and easily collapsible .
Blood pressure is high in arteries	Blood pressure is low in veins
