B is the correct answer i believe
The bond in NO3- ion is polar covalent and oxygen pulls the electrons.
A polar covalent bond is formed when there is a significant difference in electronegativity between covalently bonded atoms.
Such bonds are said to be polar covalent with the electron density tilted towards one of the bonding atoms.
In NO3-, Nitrogen and oxygen have an electronegativity difference of 0.5, so the bond is polar covalent, with oxygen pulling the electrons toward it.

The type of bond is determined based on if the bond is between an metal and a non-metal, or two non-metals. The metal-nm bond is ionic, and the two non-metal bond is covalent. Therefore:
NaCl - ionic
I2 - covalent
HCl - covalent
KF - ionic
