Best answer
The correct answer is (a) True

The best I can explain: Heat and the head pressure of molten metal can make a variation in the dimensions of casting, the heating and cooling of molten metal which results into expansion and contraction of it respectively, this changes the volume of a mould cavity and further results into the undesired dimensions of the casting.
