Which of the following stack operations is not likely to cause an exception to be thrown? A. adding an item to the stack when the stack is full B. adding an item that has the same value as one that is already in the stack C. removing an item when the stack is empty D. all of a), b), and c) E. All of these are likely to cause an exception to be thrown

The operation that is not likely to cause an exception to be thrown is B. adding an item that has the same value as one that is already in the stack.

Here's why:

A. Adding an item to the stack when the stack is full - This operation is likely to cause an exception because most stack implementations have a size limit. If you try to add an item to a stack that is already full, it will likely throw an exception indicating that the stack is full.

C. Removing an item when the stack is empty - This operation is also likely to cause an exception. If you try to remove an item from a stack that is empty, it will likely throw an exception indicating that the stack is empty.

B. Adding an item that has the same value as one that is already in the stack - This operation is not likely to cause an exception. Stacks typically allow duplicate values, so adding an item that has the same value as one that is already in the stack should not cause an exception.

D. All of a), b), and c) - This option is incorrect because, as explained above, operations A and C are likely to cause exceptions, but operation B is not.

E. All of these are likely to cause an exception - This option is also incorrect for the same reason as option D. Operation B is not likely to cause an exception.
