The correct answer is B) City B because it is a wet region and the temperature fluctuates around the freezing point
City B rocks are likeliest to experience frost wedging because its temperature fluctuates between 5°C to -4°C . Fluctuation of temperature near freezing point, frost wedging takes place when water converted into ice. Water expands when it changed in ice. As a result water continually seeps into rock cracks. The frequent freezing and melting causes Freeze-thaw. Through repeated melting and freezing of water the rocks break apart.
