Expert Answer:

option (B) is correct.
 
Given:
 
Mass of gas 'X' = 10 gm
 
Mass of H2 = 2 gm
 
We know,
 
Vapour density is given by,
 
Vapour space density space equals space fraction numerator Mass space of space straight a space gas space apostrophe straight X apostrophe over denominator Mass space of space hydrogen end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 10 over 2
Vapour density = 5
 
Relative molecular mass of gas 'X' = Vapour density × 2
 
                                                  = 5 × 2 = 10
