Answer:

The correct option is Option B i.e. the molecular weight of oxygen is half that of Sulphur dioxide.  

Explanation:

Oxygen molecule is formed of two atom of oxygen. "Atomic weight of oxygen is 16".

So, Molecular weight of oxygen =16 \times 2=32

Sulphur dioxide is formed of one atom of Sulphur and two atom of oxygen. Molecular weight of sulphur is 32.

Molecular weight of Sulphur dioxide =32 + 16 \times 2=32+32=64

So, the molecular weight of oxygen / molecular weight of Sulphur dioxide  

=\frac{32}{64}=\frac{1}{2}

So, weight of oxygen is half that of "molecular weight of Sulphur dioxide".
