Given below are two statements :

Statement I : $$\mathrm{SO}_{2}$$ and $$\mathrm{H}_{2} \mathrm{O}$$ both possess V-shaped structure.

Statement II : The bond angle of $$\mathrm{SO}_{2}$$ is less than that of $$\mathrm{H}_{2} \mathrm{O}$$.

In the light of the above statements, choose the most appropriate answer from the options given below:
