The correct answer is option 1.

Statement I is true because in the northern hemisphere, the ocean currents flowing from the equator towards the North Pole and from the pole towards the equator are deflected to the right. This phenomenon is known as the Coriolis effect.

Statement II is the correct explanation of Statement I because this deflection of ocean currents occurs due to the rotation of the Earth on its axis from west to east. The rotation of the Earth creates a spinning motion, which causes the Coriolis effect. The Coriolis effect is caused by the combination of the Earth`s rotation and the movement of fluids like air or water.

When fluids move in the northern hemisphere, they are deflected to the right due to the Coriolis effect. This is because different points on the Earth`s surface are moving at different speeds due to the rotation. As a result, the fluids are deflected to the right in order to maintain their velocity relative to the Earth`s surface.

Therefore, both statements are true and statement II provides the correct explanation for statement I.
