{'coriolis effect': [0, 0, 3, 1], 'wind patterns': [0, 0, 2, 0], 'southern hemisphere': [0, 0, 2, 2], 'clockwise': [0, 0, 2, 8], 'northern hemisphere': [3, 0, 0, 2]}

Option 1 suggests both the assertion (A) and reason (R) are true and that (R) correctly explains (A). This is incorrect because the wind patterns are not always clockwise in the northern hemisphere and anticlockwise in the southern hemisphere.

Option 2 also mentions both (A) and (R) are true but explanation by (R) for (A) is not correct. This is not the right answer as assertion (A) is false.

Option 3 states that (A) is true and (R) is false, which contradicts the correct answer as (A) is factually incorrect.

Option 4, the correct answer, asserts that (A) is false but (R) is true. This is correct as the wind patterns aren`t always just clockwise in northern hemisphere and anticlockwise in southern hemisphere. However, the Coriolis effect does indeed strongly influence the direction of wind patterns on a global scale. So, the reason (R) is true, but the assertion (A) is false.
