Final answer:
The term 'copy thrust' refers to the content of the advertising copy, including the main message, claims, and persuasive techniques. Option c is correct.
Step-by-step explanation:
The term 'copy thrust' refers to what is to be communicated by the words and illustrations in advertising. It encompasses the main message, claims, and persuasive techniques used in advertisements to capture the attention of the audience and promote a particular brand or product.
For example, if a car advertisement focuses on its fuel efficiency and reliability, those attributes would be part of the copy thrust. Similarly, if a soda advertisement emphasizes the refreshing and enjoyable experience of drinking the soda, that would be included in its copy thrust.
The Federal Trade Commission (FTC) may challenge the claims made by an advertiser if they are considered false or misleading, but the term 'copy thrust' itself refers to the content of the advertising copy.
