Answer:
Peripheral route persuasion.
Explanation:
The persuasive routes concept was developed by Petty and Cacioppo in 1981. They defined two routes of persuasion. They are, central and peripheral.
The peripheral route to persuasion is a form of persuasive message that is based solely on appearance. This persuasive route is not based on argument or the content of the message but peripheral cues.
In the given case, the persuasion form that can be used to convince Alexandra to buy a car would not be based on why a car is good, or the speed, etc. The contents that are usually looked by a car buyer, but on peripheral cues.
Persuading someone based on peripheral cues involves less effort as it is only slightly related to the content. A seller can persuade Alexandra by showing good-looking cars with nice stereo system.
So, the correct answer is Peripheral Route to Persuasion.
