Which molecule has both non-polar and polar bonds,but the molecule as a whole is polar?

In terms of polar character,which of the following orders is correct?

Which molecule has the largest dipole moment?

Molecular $AB$ has a bond length of $1.61\,\mathring{A}$ and a dipole moment of $0.38\,D$. The fractional charge on each atom (absolute magnitude) is $(e_0 = 4.802 \times 10^{-10}\,esu)$

If the dipole moment of $Images-1$ is $1.5 \ D$, then the dipole moment of $Images-2$ will be ................. $D$.

If the dipole moment of $HI$ is $0.38 \, D$ and the bond length is $1.61 \, \mathring{A}$,what is the percentage ionic character of the $H^{\delta +} - I^{\delta -}$ covalent bond (in $\%$)?
