问题补充：

The tourists have been to Mount Huang lost in the beautiful scenery there.

A. /; them

B. that; them

C. who; themselves

D. which; themselves

答案：

A. /; them

B. that; them

(答案→)C. who; themselves

D. which; themselves

解析：句意：去黄山旅游的游客们在那里美丽的风景之地迷路了。The tourists为先行词，定语从句中缺少主语，所以关系词用that或who；Lose oneself意为“迷路，迷失方向”；故选C。
