Best answer
Correct choice is (b) False

The best explanation: The resin used in the shell core making is allowed to melt to the specified thickness and is cured. The excess sand is dumped or removed. The hardened sand is extracted from the core. This hardened sand is good enough to perform its function and extra baking is not required.
