从语法上看,A. sunflowers standing ten feet tall, their brown heads drooped 也可以,这就理解为前为非谓语动词,属于次要成份,后为谓语动词,属于主要内容.
而D的刚好相反,stood是谓语动词,表明前半部分是主要的,drooping是非谓语动词,表明后半部分属于次要的.
按照常理,sunflowers 是整体,且首先出现,当属主要的,而their brown heads 是部分,后出现,当属次要的.所以正确的是D.

我的分析是独立主格结构,从句是一种(花心)垂下来的状态,因为是主动,所以分词为ing形式。C.E选项中不能加and,独立主格结构中没有加了逗号还有and。B选项主句不是句子,你发现没有谓语. 你看看,咱再交流哈
