Correct option is (b) False

For explanation: In continuous casting technology, metallic mould is generally preferred. The solidification is initiated in a water-cooled open-ended copper mould. And the casting which gets shaped in the mould includes a core of liquid metal which slowly solidifies as the strand moves through the caster during the solidification.
