这个是独立主格结构 解释是正确的
首先一个句子在没有连词的情况下,只能有一个谓语动词.
着句话前面已经有了has already sent up做谓语动词了,逗号不能连接两个完整的句子,所以A答案是最迷惑的,如果是分号或者有个连词and就可以用A.
如Everyone being ready,the teacher began his class.后面一句是个完整的句子,前面一句谓语就用ing分词的形式做伴随状语.相当于when everyone is ready.
The boy leading the way,we had no trouble finding the strange cave.这句也是一样,the boy leading the way也是独立主格,不过是做原因状语.相当于beasue the boy led the way
My health allowing,I will work far into the night.这个前面部分也是独立主格结构,不过是做条件状语,相当与if my health allows .
注意如果有连词了,句子的谓语动词和做独立主格的句子的"谓语部分"的区别.
正如你的题目所说，这道题考的是非谓语。
如果选A，前后是两个句子，中间是逗号就必须加连词and
而doing形式作主动性的非谓语来做状语，而不是一个句子
