Answer:
B). Place quotation marks around any three words or more in a row that she quoted from the website and include a parenthetical citation every time.
Explanation:
Plagiarism is exemplified as the process of copying or imitating someone's idea, thoughts, words, or language without appropriately acknowledging the author or the work from where the information has been used/copied. It is considered as an offense in literary context to copy someone's idea without acknowledging the source and leads to shaking the credibility or reliability of the claim as well as the author.
As per the question, to avoid plagiarism Etta needs to 'put the quotation marks after every three words or extra in continuity for the information that has been quoted from the website along with a parenthetical citation.' This would reflect that she has acknowledged the sources aptly that she has referred to in her essay. This would further assist in establishing the credibility of her claim. Therefore, option B is the correct answer.
