Hey there!

The answer to your question is option C.

"Volcanologists agree that eruptions still cannot be predicted with absolute certainty" would need a citation.
"The landing on the moon is one of the most exciting events in recent history" and
"Washington, D.C. is the capital of the United States" do not need a citation.

Final
Option "C".

Hope this helps you.
Have a great day!

C. Volcanologists agree that eruptions still cannot be predicted with absolute certainty certainly is an option that needs citation in research paper. Because you are not qualified enough to make such claim without citation. Else, no one will agree with you.
