Which of the following is considered common knowledge and does not typically require citation?

The correct choice identifies information that is widely accepted and generally known within the public domain, such as the capital of France being Paris. Common knowledge includes facts that most people are expected to know and that can be easily verified, making them unnecessary to cite in academic or formal writing.

Information like this is part of a shared understanding and does not originate from a particular source, which differentiates it from more specialized or contested knowledge like findings from unique research or new theories proposed by fellow researchers, which require attribution to their original contributors. Similarly, while historical events might also seem to fit under the umbrella of common knowledge, the context and specifics of the event can vary in how widely known they are, thus they might still require citation depending on the audience and the details provided.
