Given below are statements about some molecules/ions.

Identify the CORRECT statements.

• (A)The dipole moment value of $\ce{NF3}$ is higher than that of $\ce{NH3}$.
• (B)The dipole moment value of $\ce{BeH2}$ is zero.
• (C)The bond order of $\ce{O2^{2-}}$ and $\ce{F2}$ is same.
• (D)The formal charge on the central oxygen atom of ozone is $-1$.
• (E)In $\ce{NO2}$, all the three atoms satisfy the octet rule, hence it is very stable.
