Dereferencing a variable that is not a pointer cannot cause a fatal execution-time error because a non-pointer variable does not have a memory address to dereference. Option A, B, and C can cause fatal errors as the pointer is either pointing to an uninitialized or null memory location or an invalid memory location.
