<h3>What are in-text citations?</h3>
Citation is the indication of the sources used to write the information. In the text, citations are the inclusion of the resource source in the body paragraph itself that is different from the references included at the end.
In the body of the work, the brief form of references is written and is best represented in the last sentence where appropriate quotation marks and brackets.
Therefore, the last sentence is the best-revised example.
