Asource must be cited a. only if a direct quote is used c. there are no “musts” when it comes to citing sources b. only if an author was listed when you found the information d. a source should always be cited

The correct answer is d. A source should always be cited

Explanation:

A source refers to any online or printed material you use to write a paper, for example, an essay, academic article, research, etc. According to academic writing rules, all sources must be cited because in most cases you will include information from the sources in your paper or work, and by not citing the source you will be incurring in plagiarism (copying someone else's ideas). In this way, citing is a must if you include a direct quote, paraphrase, summarize or use the information of another source because by citing you acknowledge the original author of the source.
