Best answer
The correct option is (c) Flash

Explanation: Flash is a term which is used for the excess metal forced into the parting plane. Before using the castings, it is very necessary to remove flash together with any overflow present in the casting. This problem can be solved by implementing low-pressure die casting method, where the condition of excess metal cannot be possible due to upward flow of molten metal.
