Which of the following is an example of a promotional method?

The correct answer is personal selling because it directly involves interactions between a salesperson and potential customers with the intent of promoting and selling products or services. Personal selling is a promotional method that allows for a two-way communication, where the salesperson can tailor messages to meet the specific needs and concerns of individual customers. This method is highly effective as it builds relationships and trust, helping to increase sales and ensure customer satisfaction.

In contrast, market research focuses on gathering and analyzing information about consumers and market trends to inform business decisions, but it is not a promotional method itself. Product development involves creating and refining products to meet market demands, which is critical for success but does not inherently involve promoting products. Logistics planning addresses the processes involved in the distribution and delivery of products, ensuring that goods reach the customers efficiently, rather than promoting or marketing them.
