个人感觉e，没有必要因为being排出他，作主语的时候只能这样说

c it指代问题

那么有人能对这道题目提点看法么？

C is the right one

E:    Being heavily committed to a course of action, especially one that has worked well in the past, is likely to make an executive miss signs of incipient trouble or misinterpret them when they do appear.

here we can not find a logical subject to the participle being at the beginning of the main clause. That is a big foult

C:  An executive (who is heavily committed to a course of action) is likely to (miss or misinterpret signs of incipient trouble when they do appear,)  especially if it has worked well in the past.

the clause behind the especially is an adverbial modifier clause, and we can find out the main structure like this.  Adverbial modifier clause always modifies the whole main clause, so we can see "it" clearly refered to the subject of the main clause "an executive" here. So it is the right answer. 

恩 总算有人回答了，感动~~T_T

可是疑问仍然存在。。

being不好的原因是由于可以省略，但这里being不能省略貌似，他做主语，而不是状语，省略了意思也就不对了阿~　至于one。。问什么不好？

至于c里面的it。。真的是指代不清阿。。绝对没有e里面的one好~

being a farther of 12 boys is likely to drive a person mad.

a father of 12 boys is likely to drive a person mad.

为什么现在论坛上都倾向于问问题而不是解决问题呢？

今天看看e的确有点不舒服~　＝＝．．

e根本就没有主语

C:  An executive (who is heavily committed to a course of action )is likely (to miss or misinterpret signs of incipient trouble when they do appear, )especially if it has worked well in the past.

the clause behind the especially is an adverbial modifier clause, and we can find out the main structure like this.  Adverbial modifier clause always modifies the whole main clause, so we can see "it" clearly refered to the subject of the main clause "an executive" here. So it is the right answer.

厄，虽然认为c不错，可是还要指出。。这里的it按我理解 指a course of action.

而且e有主语

being a farther of 12 boys is likely to drive a person mad. 为什么说being开头的就不能是主语？

it的指代是不是有问题我还是不确定，因为后面还有trouble 而且离it近
