Best answer
The correct option is (a) True

The explanation: In the process of casting different materials, due to complexities of material behavior, internal liquid metal pressure and the mould geometry make the calculation more difficult to obtain the air gap at the interface. To solve this, proper care is to take during the process of casting products.
