Answer:
b. History is a dynamic field in which new sources and new perspectives challenge what we thought we knew about the past.
Explanation:
Among the given statements about history, the correct or true one is sentence b. This sentence states that<em> "history is a dynamic field in which new sources and new perspectives challenge what we thought we knew about the past."</em>
History may refer to the information of facts about past events. But there is no fixed nature of history. Rather, it changes with time, where new sources or information may arise and lead to new ways of interpreting or viewing it. Therefore, it is a dynamic field where new developments challenge the old ones, at times changing the perspectives and providing new insights into what we thought or knew about the past.
