Answer:
The correct answer is Option A: (Barrett, 1991, p. 17)
Step-by-step explanation:
In-text citations can be placed at the end of a quote or a sentence. They include author's last name, year it was written and then the location (which is the page number, or DVD disc number or video time) inside a parenthesis. We include in-text citation if we refer to a quote or we summarize something from another source. It basically means one is giving credit of that particular phrase or idea to the original author. There must be a corresponding entry of the in-text citation in the reference list.
It is written as (Author's last name, year and then location). Option A has all three: author's name, year and then location which is page 17 here (Barrett, 1991, p. 17).
