The correct answer is B. Postman argues that television commercials do not use language or "tests of truth" to viewers decide whether to buy a product. instead, they rely on images to create an emotional appeal that influences consumers' decisions (postman, 1985: 127-128).
Explanation:
To avoid plagiarism you need to reference the author, this means mentioning the name of the author and including the last name, date of publication, and pages in a parenthesis at the end of the citation. Also, if the exact words of the author are included rather than only a summary or paraphrase of these it is necessary to enclose the exact words in quotation mark (").
According to this, the option that is not a plagiarized version is B, because this reference the author correctly in (postman, 1985: 127-128) and uses the quotation marks when the exact words of the author are used. Also, in other options, the author is not referenced and the exact words of Postman are used without the quotation marks.
