Final answer:
The option 'e) Tell other people about the product' is not a step in the consumer buying decision process, as this action usually occurs after the purchase and is not a recognized step in the decision-making itself.
Step-by-step explanation:
The consumer buying decision process typically includes the following steps: acknowledging that a problem or need exists, searching for information, evaluating alternatives, making a purchase, and post-purchase evaluation. However, one step listed is not typically recognized as part of the consumer buying decision process. Telling other people about the product is not strictly a step in the decision-making process itself; it is a potential action that can occur after a purchase and is related to word-of-mouth communication or marketing, but it is not considered a step in the decision-making process.
