A recent poll indicates that many people in the United State

OPTION A- CORRECT
This being more of a direct speech makes it the right answer. It is being stated that they denounce the big government by saying the government is doing too much have become too powerful. This, however, means even as they are doing too much, they remain powerful at it and at the same time show support to the government. Be that as it may, the underlined is more detailed with adverbial clause properly placed, and thus making it more accurate.

OPTION B- INCORRECT
Looking at the introduction of hyphen in the sentence. The hyphen is a punctuation mark used to join words and to separate syllables of a single word. The most popular use of a hyphen is to join two compound adjectives. Whereas the words in the sentence doesn't portray such.

OPTION C - INCORRECT
Having some similarities with option would have justified this option, buy "say" as an interactive verb that bridges most noun wasn't descriptive enough to bridge the adverbial clause as seen in the underlined.
The most common introductory word groups are clauses or phrases which function as adverbs, telling how, why, when, where or under what conditions something happened.

OPTION D - INCORRECT
Let's make a reference to "while" which start up the sentence. "while" could serve as a noun or subordinating conjunction and it mainly depends on the purpose of its usage. Thus, "while" starting the sentence devoid the reason or the purpose of the people denouncing the government.

OPTION E - INCORRECT
The introduction of "while" in the sentence changed and reconstructed the actual meaning of the sentence and this is not supposed to be. The original statement is an action statement which happened as one event, but the hyphen at the middle of the sentence seemingly describe the event as one that happened one after the other.
