A representative from a radio station calls you up, saying that they are doing some 'market research' about the sorts of listeners that tune into their station. The representative just wants to ask you what your favourite song is right now. When you give him your answer he thanks you for your time and hangs up. A week later the same representative calls up and asks if they can now conduct a 20-minute interview with you about the music you listen to and what you would like to hear on their station. The radio station is using:
A. the reciprocity principle.
B. the foot-in-the-door tactic.
C. ingratiation.
