The correct option is C Cold water is poured over the rim.
For fixing the metal rim on a wooden wheel of a cart, the metal rim is made slightly smaller than the wooden wheel. On heating, the rim expands and fits onto the wheel. Cold water is then poured over the rim, which contracts and fits tightly onto the wheel.
