Single-replacement reaction.

Explanation:

Single replacement reactions are in the form #A + BC rarr B + AC# because an element replaces an element in the compound and leaves the replaced element on its own.

Since the reaction given is #K + NaCl rarr Na + KCl#, this fits the single-replacement form, so it is a single-replacement reaction.
