B.

C.
Not known by them, is that the creation of the statue took lots of years and much effort to complete.
D.

B. What many do not know is that creating the statue took many years and much effort to complete.
To create a more formal tone, the sentence should be revised by removing the informal phrase "they may not know" and replacing it with "many do not know." The passive voice construction "not known by them" in option C should be avoided in formal writing. Option A uses the phrase "to many" which is less formal than "many do not know." Option D has a misplaced modifier with the phrase "creating the statue," which makes the sentence unclear in its intended meaning. The revised sentence in option B is clear, concise, and maintains a formal tone.
