Step-by-step explanation:
The validity of a source is not directly affected by currency. The accuracy and reliability of a source depend on factors such as the purpose of the source, the perspective of the author, and the credibility of the information. Sources that have been written or updated more recently may have more up-to-date information, but it doesn't guarantee their accuracy.
On the other hand, sources that are older can still be valuable depending on the purpose of the research. Therefore, the correct option is: A source that has been written or updated more recently could have more accurate information.
