Final Answer :
B
Explanation :
The Scanner class throws an InputMismatchException if the user inputs a value that is not of the expected type. For example, if the program asks for an integer input and the user enters a string or a decimal value, an InputMismatchException will be thrown. Therefore, when using the Scanner class, it is important to account for this exception.
