Best answer
The correct option is (b) False

The best explanation: When the mould cavity is filled with molten metal and during its solidification, the final shape of the casting part is formed. The mould cannot be opened until the cooling time has elapsed. The desired cooling or solidification time can be estimated by considering the wall thickness and the temperature of the casting metal.
