Answer : The correct option is, ionic
Explanation :
As we know that the potassium element belongs to group 1 and period 4 which is a metal and the chlorine element belongs to group 17 and period 3 which is a non-metal.
The ionic compound is formed by the electrostatic force of attraction between the metal and a non-metal element.
The covalent compound is formed when two or more non-metal elements share their valence electrons.
Hence, the bond formed between the potassium and chlorine is, ionic bond.
