What does the author describe as an instance of "Guerilla marketing”?
Nike's use of Swoosh logo at Atlanta in the arena when it was sponsored by Champion
This term is used in the third para where the author mentions – “Eight years ago in Atlanta, Nike ambushed basketball sponsor Champion by sneaking giant Swoosh signs into the arena. When the cameras panned the stands, TV audiences saw the Nike logo loud and clear, while Champion had nothing”. This is indicative of guerrilla tactics where Nike used clever tricks to steal Champion’s thunder. This makes choice (d) correct.
