When using switch expressions with enums in Java 17, what happens if you omit a case and there is no default?

Answer and explanation
Correct answer
C. The code fails to compile due to non-exhaustiveness.
Why
Switch expressions with enums must cover all possible enum values, or include a default case. If neither is done, the code will not compile, ensuring all cases are handled explicitly.
