The default switch case is a case that is executed when none of the other cases in a switch statement match the given condition. It serves as a fallback option when no other case is satisfied. Here's an example: ```java int day = 3; String dayName; switch (day) { case 1: dayName = "Sunday"; break; case 2: dayName = "Monday"; break; case 3: dayName = "Tuesday"; break; default: dayName = "Invalid day"; break; } System.out.println(dayName); // Output: Tuesday ``` In this example, the switch statement checks the value of the variable `day`. Since `day` is equal to 3, the case `3` is matched, and the variable `dayName` is assigned the value "Tuesday". If none of the cases matched, the default case would be executed, and `dayName` would be assigned the value "Invalid day". Regarding the multiple-choice options, the correct answer would be: d) All afirmations are correct.
