请在( )中编写代码实现递归函数倒叙(从后向前)输出单链表内容.void pRight2Left(linklist head){if(head->next){( ____)}}

A. printf("%5d",head->next->data);pRight2Left(head->next);
B. pRight2Left(head->next);printf("%5d",head->next->data);
C. pRight2Left(head);printf("%5d",head->data);
D. printf("%5d",head->data);pRight2Left(head);
