Best answer
The correct choice is (c) Water channels cooling

The explanation is: As the metallic die is used in the die casting as a mould, so the extraction of heat from the molten metal will not be easy. So for maintaining proper die temperature, water cooling channels are used near the castings through the cover and ejector die. This makes the proper solidification of the castings.
