{'coriolis effects': [0, 0, 0, 1], 'coriolis effect': [0, 0, 3, 1], 'equator': [10, 0, 6, 7], 'rotational velocity': [0, 0, 0, 2], 'latitudes': [3, 0, 0, 0], 'poles': [5, 0, 7, 15]}

The correct answer is option 1, which states that statements 1, 2, and 3 are correct.

Statement 1 states that the Coriolis effect is zero at the Equator, which is true. The Coriolis effect is caused by the rotation of the Earth, and it influences the movement of objects across the Earth`s surface. At the Equator, which is the widest point on the Earth, the rotational velocity is highest, causing the Coriolis effect to be negligible.

Statement 2 states that the Coriolis effect is more pronounced towards the Poles, which is also true. As you move towards the Poles, the rotational velocity decreases, causing the Coriolis effect to become more significant. This is why weather patterns and ocean currents are strongly affected by the Coriolis effect near the Poles.

Statement 3 states that the Coriolis effect is related to the decreasing rotational velocity with increasing latitudes, which is true. The Coriolis effect depends on the difference in velocity between different latitudes. As the rotational velocity decreases towards the Poles, the Coriolis effect becomes stronger.

Statement 4 states that the Coriolis effect is related to the increasing rotational velocity with increasing latitudes, which is incorrect
