Answer 1

The correct option is (d) All of the mentioned

For explanation: The green sand has an adequate amount of water which is lost during the process but it can be restored by adding the same and it is fit for reusing. This enables it to be usable for longer production at less cost. Hence, the green sand molding is employed in most foundries.
