The correct answer for the given question is option 1, which states that only statement I is correct.

Statement I says that it is easier to stop bleeding from a vein than from the artery. This is because veins have thinner walls and lower pressure compared to arteries. When we apply pressure or use techniques like compression or elevation, it can effectively stop bleeding from a vein. On the other hand, due to the thicker walls and higher pressure in arteries, it may be more difficult to stop bleeding from an artery.

Statement II, which suggests that this is because veins carry deoxygenated blood, is not correct. The oxygenation or deoxygenation of blood does not affect the ease of stopping bleeding from veins or arteries. It is primarily the structural and functional differences between veins and arteries that determine the ease of stopping bleeding. Therefore, option 2, which suggests that both statements I and II are correct, is incorrect.
