This question was posed to me by my school principal while I was bunking the class.

I'm obligated to ask this question of Methods of Making Cores in division Sand Moulding of Foundry and Forging

Answer 1

Correct choice is (c) Aluminum

Easy explanation: The cores produced in the core blowing machines are produced due to the air at high velocity. It is important that the air has to be let out through the vents. The method of forming vents is easily done in aluminum. Hence the core boxes are made up of aluminum.
