At the foot of the mountain ______. A. stood a village B. a village was C. did a village stand D. stand a village

正确答案是 A. stood a village。

这是一个完全倒装句。当表示地点的介词短语放在句首时，句子可以全部倒装，即把谓语动词提到主语前面，且不需要助动词。
“At the foot of the mountain stood a village.”
= “A village stood at the foot of the mountain.”

选项 B 语法正确，但一般不会这样用，因为地点状语在句首时使用倒装更自然、更文学化。
选项 C 用了助动词 did，但 stand 是不及物动词，这里是完全倒装，不需要用助动词构成倒装。
选项 D 动词用 stand 原形，但主语是单数 a village，时态也不匹配。
