Correct answer & explanation

✓

The switch expression must be terminated with a semicolon.

Switch expressions in Java must be terminated with a semicolon, as they produce a value that is assigned to a variable. The given code uses the arrow syntax (->) and assigns the result to a String variable, so a semicolon is required at the end of the entire switch expression.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The switch expression is not allowed with a colon.
Why it's wrong here
Switch expressions can use either colon or arrow syntax; colon syntax is allowed.
✓
The switch expression must be terminated with a semicolon.
Why this is correct
A switch expression is a statement that must end with a semicolon.
✗
The default branch is optional.
Why it's wrong here
The switch expression must be exhaustive; since not all enum constants are covered, a default branch is required.
✗
The arrow operator requires a yield statement.
Why it's wrong here
In arrow syntax, the value is provided directly after the arrow; yield is not used.
