Here, consider presenting the underlined statement in active tone rather passive tone. Have been is passive and it should be written in active voice.

Option A - Incorrect
This is a passive sentence and also, the subject is wrongly placed. it's just like saying that investigation has found that that hospitals break the laws not state offices or the twelve hospital as this sentence implies. Also, the many... and that is not parallel/

Option B - Incorrect
This statement gives different meaning to the original statement in consideration. The state medical officials do not work with nor belong to the "12 hospitals" in question. The investigation was carried out by the state medical regulatory team and not members of the hospitals as being interpreted in this option.
Also, the usage of verb is wrong too. 'Investigation' is singular and should have attracted a singular verb 'has' rather than 'have'

Option C - correct
This option is in active voice. Also, the use of 'has found' which goes right well with 'investigation' that is also singular.
It's concise and follows parallelism.

Option D - Incorrect
This option has parallelism issues and it does not follow suits. The subject is not rightly placed. Also, the sentence is too wordy.

Option E - Incorrect
Wrong sentence construction and imperfect sentence linkage.
