The correct answer is Entry A. Halpern, Howard M. Cutting Loose. New York: Simon and Schuster, 1977. Print.
Explanation:
In writing, it is common to use ideas or words of other authors to support own ideas; however, ideas taken from other sources and authors cannot be used without acknowledging authorship. This is usually included by adding some information such as the author's last name and the number page during in-text citation and including a works cited page at the end of the document with entries that provide further information about each of the sources used during the paper; however, the type of information included is not the same in all cases and mainly depends on the type of source.
In the case of printed book by one author the MLA manual which is the manual commonly used to write and publish academic document establishes it is necessary to include the name of the author (last name first), the name of the book, the city of publication, the publisher, the year of publication and the word print. Besides this, other specific guidelines in terms of punctuation should be followed this includes separating the last name from the first name of the author using a comma, then adding a period before writing the name of the book then using period again to introduce the city of publication, using colon to introduce the publisher, followed by a comma to introduce the year and finally a period to introduce the word "Print". Considering this, the entry that is completely correct is "Halpern, Howard M. Cutting Loose. New York: Simon and Schuster, 1977. Print" as the information of the source has been included in the correct order and following the punctuation marks required.
