Historians have a difficult task, if not all facts have been discovered yet, with doing what?

not publish the findings until all evidence and facts are discovered

Option C. Historians have a difficult task, if not all facts have been discovered yet, with the attempt to re-create a historic event to find what probably happened.

Explanation:

Historians have been studying and investigating different historical events of civilization for centuries, with the first recorded historians being in Ancient Egypt and Mesopotamia. The main objective for any historian is to discover and gather the biggest amount of facts and evidence that can help them re-construct a specific event or moment in history. This comes with its challenges, as sometimes it is very difficult or even impossible to have every fact about an event that has happened many years ago. For those situations, historians have been re-enacting that specific even they are investigating, in order to discover and find out what could possibly have happened during that time.
