It would be safe to have a driver for this search function, in the case:

``` 1 bool search( Node ptr, Bird & bird, Bird dove ) 2 { 3 if ( ptr == NULL ) 4 return false; 5 if ( ptr->info == dove ) { 6 bird = ptr->info; 7 return true; 8 } 9 return search( ptr->next, bird, dove ); 10 } ``` which is called for a linked list (where start points to the first node) using the lines of code: ``` if ( search( start, bird, dove ) ) cout << “search successful” << endl; ``` A. that the linked list is empty B. that there is no dove in the linked list C. A driver would not help to safeguard against any adverse conditions. D. that there is more than one dove in the linked list
