String product = "Laptop";
String warranty = switch (product) {
case "Laptop" -> { yield "2 years warranty"; }
case "Phone" -> { yield "1 year warranty"; }

D. Compilation error
Why
The switch expression lacks a default case to handle cases not explicitly listed, leading to a compilation error for non-exhaustiveness when the variable does not match any specified case.
