Answer Details
The most active agent of physical weathering of rocks in arid regions is wind. In arid regions, there is little to no vegetation to protect rocks from wind erosion, so the wind can easily blow away loose sediment and small particles, slowly breaking down rocks over time. This process is known as deflation and is a common feature in deserts and other arid regions. Therefore, option C - wind is the correct answer.
