She to Shanghai on business.
A. have been B. has gone C. has been

解析：此题重点考查have been to和have gone to的区别。have been to：曾经去过have gone to ：去了（表示现在在那个地方）have been to可以用任何人称 have gone to不能用在第一、第二人称 have been to为去过，表示回来了 have gone to为去了，表示还没回来 去过，回来了”用been，“去了，没回来”用gone,两者均可后接地点，前者表示去过某地，通常可与表示次数的状语连用；后者表示到某地去了，强调说话的当时去某地的人不在场
