During which sales method can product demonstrations be showcased to consumers?

The sales method where product demonstrations can be effectively showcased to consumers is personal selling. This approach involves direct interaction between a salesperson and potential customers, allowing the salesperson to tailor their communication and presentation based on the customer's needs and preferences.

During personal selling, product demonstrations provide a hands-on experience that highlights the features and benefits of the product, helping customers understand how it can solve their specific problems or enhance their lives. This interactive format also allows for immediate feedback and the opportunity to address any questions or concerns, thereby increasing the likelihood of making a sale.

In contrast, the other methods listed—Quality Assurance, Benchmarking, and Quality Control—focus more on evaluating processes, standards, and performance metrics rather than engaging directly with customers to promote and demonstrate products.
