I believe your answer will be (B) Frost Wedging - and temperature plays a roll in the freezing of water in the cracks of rocks, causing Frost Wedging.
We know that volume of a mass of ice is more than the same mass of liquid water
When water freezes its volume increases
in rocks at low temperature the water present in the cracks of rocks expands increasing the gap of cracks further. this is known as frost wedging
Thus frost wedging is a result of temperature
