Solution
The correct option is C A and C only
Thermoplastics have no cross-linkage and are soft, while the thermosets have cross-linkages and are hard in texture.
Thermoplastics get deformed easily on heating, whereas, thermosets when moulded once, cannot be moulded again on heating. So, both the materials are able to withstand heat, but behave differently on application of heat.
