选C
首先判断时态,yet是完成时一种标记
并列主语表示同一概念时,后面用单数,所以用has
例如:Bread and butter is served for breakfast.
早餐有提供面包和黄油
Early to bed and early to rise is a good habit.
早睡早起是好习惯

选a比较接近,因为decided需要被动。

答案是C
看到 yet... 就要联想到语法是"否定" "完成"式... has/have not V+ed yet... 再来决定主词的单复数问题... when and where to build the new factory 讲的是一件事情... 所以用单数... 答案就是 has not decided yet... 这样说明希望LZ很容易能理解解题技巧... 并祝福您学业精进...
