to sun, rain and wind for a long time, the stone split（裂开）.

A. Being exposed

B. Having exposed

C. Exposed

D. To expose

答案：

A. Being exposed

B. Having exposed

(答案→)C. Exposed

D. To expose

解析：考查分词用法。The stone与Expose，构成被动关系，故使用过去份被动被动。排除BD。A项表示正在被暴露，本题不强调正在进行。句意：长时间被暴露在阳光，雨水和大风之中，这块石头裂开了。故C正确。
