An in-text citation typically includes the name of the author (or the website if no author is available) and the year of publication, but it does not include the title of the source, the publisher, or the number of pages. The specific format can vary depending on the citation style being used (such as APA, MLA, or Chicago). For example:
- In APA style, an in-text citation might look like this: (Smith, 2020).
- In MLA style, it might look like this: (Smith).
Hence, the correct answer is primarily the name of the author or website.
