I choose option D.

Can anyone explain why C and E are wrong, I think the word 'having' is wrong.

Answering Samrat123456:
Here's what I think:
C. professor announced that some of the students, having clearly cheated on the exam,
Take out the section between commas and you have this: "professor announced that some of the students all would have to retake it." ALL is wrong, delete it and changes the meaning.

D. professor announced that since some of the students had clearly cheated on the exam,
Correct because past perfect "had clearly cheated" is the appropriate tense in the sequence of events.

E. professor, announcing that some of the students, having clearly cheated on the exam,
Wrong because "announcing" is not parallel with the preceding simple past tense: "Once the police made public..." and because "since" is missing.

Vilamari is correct. I don't think 'having' is immediately incorrect (though it's unusual).

I think the sentence "Once the police made public the details of the hacking of the university computer, the chemistry professor announced that some of the students, having clearly cheated on the exam, would have to retake it." would be totally fine.

The issue is that C doubles up on a subject.

"[The professor announced that] **some of the students** ..."

{okay Reed wants to know what 'some of the students' did}

"...**all** would have to retake it."

That part is outside of the underline, so there's no fixing that---'all' is the subject of 'would have to retake.'

So C is out.

NOTE: "that" has many uses, but when you get the sense it's about to start a new clause, 'reset' into structure mode. Find subjects and verbs! They are king and queen of sentence structure:

"He believes that..."

"The company knows that..."

"It was surprising that..."

"Nobody could see that..."
