Final answer:

Potassium and iodine react to form potassium iodide (KI), which is an ionic compound.


Step-by-step explanation:

The correct answer is B. They form the compound KI, which is ionic. Potassium (K) and iodine (I) react to form potassium iodide (KI). In this compound, potassium loses one electron (becoming K+) and iodine gains one electron (becoming I-), resulting in the formation of an ionic bond between them.
