In which of the following pairs is the product of the Lewis acid and Lewis base reaction also a Lewis base?

What are the different types of bonds formed by sulphur with oxygen in thiosulfuric acid $(H_2S_2O_3)$?

Given below are statements about some molecules/ions. Identify the $CORRECT$ statements.
$A$. The dipole moment value of $NF_3$ is higher than that of $NH_3$.
$B$. The dipole moment value of $BeH_2$ is zero.
$C$. The bond order of $O_2^{2-}$ and $F_2$ is same.
$D$. The formal charge on the central oxygen atom of ozone is $-1$.
$E$. In $NO_2$, all the three atoms satisfy the octet rule, hence it is very stable.
