Best answer
Correct answer is (a) Mechanical

For explanation: The prepared shells are joined together by mechanical clamping or sometimes adhesive bonding is also preferred for joining of shells. The resin used as an adhesive may be applied at the parting plane before mechanical clamping and then allowed for 20 to 40 seconds to achieve necessary bonding. Then the shell mould becomes ready for pouring of molten metal.
