The correct answer is option 4, which states that all three characteristics are associated with cyclones in the Northern Hemisphere. Let`s analyze the options to understand why this is the correct answer:

Option 1: This option suggests that only characteristic 1, which is low pressure in the center of the cyclones, is associated with cyclones in the Northern Hemisphere. However, this is incorrect because all three characteristics are present in cyclones in the Northern Hemisphere.

Option 2: This option suggests that characteristic 2, which is the inward spiral of surface winds, and characteristic 3, which is the anti-clockwise direction, are associated with cyclones in the Northern Hemisphere. This option correctly identifies two out of the three characteristics, but it misses out on characteristic 1, which is also present in cyclones in the Northern Hemisphere.

Option 3: This option suggests that only characteristic 2, which is the inward spiral of surface winds, and characteristic 3, which is the anti-clockwise direction, are associated with cyclones in the Northern Hemisphere. This is incorrect because characteristic 1, the low pressure in the center of the cyclones, is also associated with cyclones in the Northern Hemisphere.

Option 4: This option correctly states that all three characteristics,
