Why the other choices are wrong
Choice A
Choice A is incorrect. The sentence explains that Aeolian landforms are created by wind but does not provide an example of any specific Aeolian landforms. Rather, the example it provides is of a wind-based process.
Choice C
Choice C is incorrect. While the sentence provides a partial explanation of Aeolian landforms, noting that they are created by the wind, it does not effectively provide an example. The sentence seems to indicate that mushroom rocks, rather than being an example of Aeolian landforms, are distinct from them.
Choice D
Choice D is incorrect. While the sentence provides an explanation of a mushroom rock, which is a specific example of an Aeolian landform, it doesn’t provide an explanation of Aeolian landforms in general.
