In the given diagram of a mushroom rock, we are asked to identify the point where the intensity of wind is strongest. Option 2 (B) is the correct answer.

To understand why option 2 is the correct answer, we need to analyze the structure of the mushroom rock. A mushroom rock has a distinct shape with a narrow stem and a wider top resembling a mushroom. This unique shape is created by years of erosion caused by wind and water.

In this case, the narrow stem of the mushroom rock acts as a funnel, where the wind gets channeled and its intensity increases. As the wind passes through the narrow opening or gap, it gets squeezed, resulting in a stronger wind flow.

Therefore, the point on the diagram corresponding to option 2 (B) represents the narrow stem of the mushroom rock. As the wind passes through this narrow passage, the intensity of wind is strongest at this point.

Alert - Correct answer should be option 1 (A). The narrow stem of the mushroom rock would lead to an increase in wind speed and intensity at point A.
