The correct option is C 1 ionic, 3 covalent, and 1 coordinate
From the Lewis structure, it is clear that 3 covalent bonds (one in between nitrogen and each of the three hydrogens around them), 1 coordinate bond (in between nitrogen and one of the hydrogens), and 1 ionic bond (in between ammonium cation and chloride anion) is present in ammonium chloride.
Therefore, the option ‘c’ is correct.
