Molar volume defines the volume occupied by one mole of gas.  Therfore it's an extensive variable. Temperature and pressure don't depend on amount of substance and hence are intensive properties. Internal energy and enthalpy depend on amount of gas, so they are extensive properties.  Heat capacity, since it's not mentioned whether Molar or specific, we can say that it's dependant on miles of gas.  
So the appropriate choice is (2) 4.
