Answer:
D. A citation of the magazine article.
Step-by-step explanation:
This is courtesy and a tag to a good write to always find a way to cite his work in any form as this shows a great deal of purpose and also express broadly where the idea came from as it stands as a backup proof to show your expression gather stances from other experienced people. This also directly gives honour to whom it is due. In this act writing the original author's full name cannot be over emphasized; writing all parenthesis and commas involved too. All citations should also match the style you are using exactly, including its capitalisation, italics and bolding formats, as same referencing style should be used throughout your assignment.
