Answer:
The correct option is: "Smith (2005) stated, "The rules and regulations clearly mandate..." (p.67).
Step-by-step explanation:
- "Dobson stated, in his persuasive documentary, "we will countribute to..." (p.78)" WRONG = because it doesn't include the year of publication next to the surname of the author.
- "Alex (1999) said, "after all this time, I find it hard to believe the theory of..." WRONG = because it doesn't include the page number from where the quotation was taken.
- "Matthews said, "The research study results were inconclusive" (para. 4) WRONG = year of publication is missing, and the quotation is too short to refer to a whole paragraph, always when using quotation you must include the page number and year of publication.
