Question Description
The following function reverse() is supposed to reverse a singly linked list. There is one line missing at the end of the function./* Link list node */struct node{ int data; struct node* next;};/* head_ref is a double pointer which points to head (or start) pointer of linked list */static void reverse(struct node** head_ref){ struct node* prev = NULL; struct node* current = *head_ref; struct node* next; while (current != NULL) { next = current->next; current->next = prev; prev = current; current = next; } /*ADD A STATEMENT HERE*/}What should be added in place of “/*ADD A STATEMENT HERE*/”, so that the function correctly reverses a linked list.a)*head_ref = prev;b)*head_ref = current;c)*head_ref = next;d)*head_ref = NULL;Correct answer is option 'A'.
