In C++, the special pointer value NULL is used to indicate the end of a linked list. This value represents a null pointer, meaning that it points to nothing, and is commonly used as a sentinel or flag to signal the end of a list. The other options (EMPTY, LAST, and ZERO) are not commonly used or recognized by the language as sentinel values. In C++, NULL is a special pointer value that indicates that the pointer is not pointing to any memory location. It is often used as a sentinel value to indicate the end of a linked list. Therefore, the correct choice is C) NULL.
