英语方面的 thanks

Her refusal was definite, ALLOWING NO ROOM for further discussion.
她的拒绝是明确的,没留任何讨论的空间.
A no room was allowed
B allowing no room
C no room been allowed
D having allowed no room
因为verb是"ing"结尾 所以"allowing no room for further discussion" 是形容前面的"her refusal was definite"
这种句型是固定的 C 和 D grammatically 都是 incorrect
如果是C 必须是 "..., no room is been allowed for further discussion" 而D的话呢 则是 "..., having no room for discussion"```
A嘛 grammar 上是对的 但是 选B听起来通顺一些
又如：
He got 100% on his test, proving that his answers were right.
他考试的了100%,证明了他的答案是对的.
等于后面“证明了他的答案是对的”是形容前面 “他考试的了100%”的
在这里 我们看到"to prove" 也是 "ing"结尾 所以形容了前面的半句话
