You work for an advertising agency. you have been assigned to come up with an advertising campaign for a new brand of designer water, which in reality is standard city reservoir water in a fancy bottle. in this case, you are best off using the route, because

The correct answer are: peripheral route; you do not have strong arguments for why your product is superior

Explanation:

The peripheral route, instead of examining the relevant arguments for the matter, individuals examine the message quickly or focus on simple indicators that help them decide whether to accept or reject the position advocated in the message. The elements that are peripheral to the arguments of the message are those that take center stage. These may include the communicator's physical attractiveness, the direct style of speaking, or the pleasant association between the message and the music that is heard in the background. Sometimes, the strength of the arguments is of secondary or almost null importance. Sometimes we lack the motivation, ability or time to reflect carefully. If we are disinterested, distracted or busy, we may not take the time to analyze the content of the message. Instead of analyzing whether the arguments are convincing, we will most likely follow the peripheral route, focusing on clues and indicators that activate automatic acceptance without too much cognitive processing. Peripheral processing allows communicators to design simple claims and messages to influence individuals. Although on many occasions this route may seem like the panacea of contemporary persuasion, the truth is that a good part of it is also carried out through mechanisms that involve careful and reflective considerations of the message's arguments, since, as we have indicated, When people have some motivation or are able to process messages, they are not based exclusively on peripheral cues and signals, or necessarily fall into the tricks of the persuader. When processing peripherally, people always rely on simple rules, to make decisions, "heuristic." For example the "heuristic" that experts should be believed and only for this reason accept the recommendation of a speaker, the heuristic "if many people think that something is good, then it should be" or those of reputation, consistency and security apparent in the argument. Peripheral and superficial processing does not produce profound and lasting changes of opinion. The effects of surface processing are ephemeral but relevant enough to convince an undecided voter or push a consumer towards the purchase of one or another product.
