Describe the geometry (shape) of some simple molecules or ions with central atoms having one or more lone pairs of electrons $(E)$.

Given below are two statements:
Statement $I:$ $SO_2$ and $H_2O$ both possess $V$-shaped structure.
Statement $II:$ The bond angle of $SO_2$ is less than that of $H_2O$.
In the light of the above statements,choose the most appropriate answer from the options given below:

Which among the following molecules is not perfectly flat?
