{'winds': [1, 0, 0, 1], 'correct direction': [1, 0, 0, 1], 'pressure conditions': [0, 0, 0, 1], 'diagram': [0, 3, 2, 5], 'above diagram': [0, 0, 1, 0], 'blow': [0, 0, 0, 1], 'movement': [9, 3, 7, 28]}

Option 1 states that the winds blow from B towards both A and C. To understand why this is the correct answer, we need to analyze the pressure conditions at each location. In the diagram, the high-pressure area is represented by the letter H, and the low-pressure area is represented by the letter L.

At location B, we can see that there is a high-pressure area (H) surrounding it. According to the principle of atmospheric pressure, air flows from areas of high pressure to areas of low pressure. Nearby location A has a low-pressure area (L) next to it, indicating that air will flow from the high-pressure area at B towards the low-pressure area at A.

Similarly, location C also has a low-pressure area next to it. Therefore, the winds will blow from B towards both A and C to equalize the pressure difference.

Option 2 suggests that the winds blow from C towards both A and B. However, this contradicts the principle of air movement from areas of high pressure to areas of low pressure, as there is a high-pressure area (H) at location C.

Option 3 suggests that the winds blow from B to A and from A to C. However, this is incorrect as it does not consider the high-pressure area
