Solution
The correct option is A Statement − 1 is true, Statement − 2 is true and Statement − 2 is correct explanation for Statement − 1. The melting point of noble gases increases as its atomic mass increases, this is because as atomic no. increases, induced dipole increases and melting point of gases become high.
