Answer:
an online article from the Journal of Southern History
Explanation:
When doing research, it is important to understand how to identify a valid source. The Internet has a wealth of information, but not all of it can be considered valid. Of the answer choices listed here, the best source would be an online article from a historical journal. Journals such as the Journal of Southern History contain articles written by historians who have thoroughly researched their subjects. These articles are also reviewed and edited by other experts on the subject matter. Sources like blogs or free online encyclopedias are not always written and edited by subject experts, so the information they contain might not be valid. For this reason, these sources should be avoided when doing research.
