How do you cite an authored book with no publication date in APA format?

When citing an authored book with no publication date in APA format, the correct approach involves reflecting the absence of a specific date in the citation. The proper format indicates this by using the abbreviation "n.d." which stands for "no date." This indicates to the reader that while the work is authored, the year of publication is not available.

The citation format begins with the author's last name followed by their initials, maintaining the standard APA structure. After the author's name, "n.d." is included in parentheses to signify the lack of a publication date. Following this, the title of the work is presented in italics, and proper capitalization rules apply where the first word of the title, the first word of the subtitle (if there is one), and any proper nouns are capitalized. Conclusively, the publisher's name follows the title. This structure not only adheres to APA guidelines but also provides clarity for the reader regarding the publication date's absence.

The other choices fail to follow the correct citation structure or misplace essential elements, thus not conveying the information in the required APA format.
