PV=nRT is the ideal gas equation
Ideal gases r thosr which have a negligible size and no intermolecular forces
If you need a close-to accurate value of Mr of a real gas....it can tend to ideal when pressure is low..so molecules are further apart and occupy negligible space and when temp is high..so again the molecules are far apart with hardly any interactions(thus satisfying the conditions of an ideal gas and hence the equation)..
So the ans is C

Hope you understood

sweetie:
