Correct choice is (b) False

For explanation I would say: In gravity die casting, liquid metal enters into the cavity by means of gravity force only, as shown in below figure. It is used to produce a simple shape of the objects made up of high fluidity materials. And due to fast rate of cooling, fine gain structure will be developed in the castings which are having more strength and hardness.
