That tree the branches are almost bare is an old o

问题补充：

That tree,the branches are almost bare,is an old one A whose B of which C in which D on which答案老师说是B 但是先行词什么啊 为什么选B 从句是从哪到哪尽量把句子里包含的语法点 说的清楚点

答案：

这个空是填在the branches前面吧,先行词是the tree,从句是the branches are almost bare

如果把语序正过来就是the branches of which are almost bare,其中which指代the tree.

至于其他选项C D明显错,A没有B好的原因是whose的先行词最好是人,而which是物
