Final Answer:
The most likely ionic compound is OXOY (Option B).
Step-by-step explanation:
Ionic compounds typically form between elements with significantly different electronegativities, leading to the transfer of electrons. In the given options, OXOY (Option B) is more likely to be an ionic compound. This is because it follows the pattern of a metal (M) combining with a non-metal (X and Y). The presence of two different non-metal elements suggests that there could be an ionic bond between the metal (O) and the non-metals (X and Y). On the other hand, OWO (Option A) and OZO (Option C) both involve only oxygen atoms, indicating a less typical ionic bonding scenario.
Option B is the answer.
