    The correct answer is option C.

    Explanation:

    Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

    The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.

    Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

    From the given options, the option with metal and non metal is potassium and chlorine. these elements will combine together to form ionic compound called potassium chloride.
