Best answer
Correct option is (b) False

The explanation: In slush casting, if porosity is present in the mould part, then it can cause detrimental effects on the casting part such as pin-holing, surface gloss reduction and voids in the casting. So, extreme care should be taken while selecting the die or for the preparation of the same.
