Answer:
B). No, if you fail to cite yourself, you are self-plagiarizing.
Step-by-step explanation:
Self-plagiarism is characterized as the use of using one's own work or intellectual material again(more than once). When the author copies certain words or ideas from his/her previously published works in another work without proper citation. In the given case, if I reuse the content of my previous paper for my assignment without citing that work, it would be considered self-plagiarism and affect the credibility of my work. Thus, it is not okay to use the content without citation.
