int productCode = 102;
switch (productCode) {
case 101: processProductA(); break;
case 102: processProductB(); break;
case 103: processProductC(); break;
}Answer and explanation
Correct answer
B. Use switch with product codes as cases and include breaks.
Why
Switch statements are ideal for checking multiple discrete values, such as product codes, and improve readability by eliminating deeply nested if-else structures. Each case should be followed by a break to prevent fall-through unless otherwise desired.
