Final answer:
When using parenthetical citations for a book, include the author's last name, the year of publication, and the page number in parentheses. The correct answers are: b. The author's last name and e. The page number.
Step-by-step explanation:
When using parenthetical citations for a book, the information that needs to be put in parentheses includes the author's last name, the year of publication, and the page number.
For example, if you are quoting from a book written by John Smith, published in 2021, and the quote is on page 45, the citation in parentheses would look like this: (Smith, 2021, p. 45).
Make sure to italicize the book's title in the reference list and only include the author's last name in the parenthetical citation.
