Final answer:
A consultative method to introduce accessories involves asking open-ended questions, recommending based on customer preferences, and explaining the features and benefits. Therefore the correct answer is c. Assuming the customer's accessory preferences without asking for input
Step-by-step explanation:
When a customer is purchasing a new vehicle, using a consultative method to introduce accessories involves asking open-ended questions about the customer's preferences and needs, recommending specific accessories based on the customer's lifestyle and vehicle choice, and explaining the features and benefits of recommended accessories.
Option c, assuming the customer's accessory preferences without asking for input, is not an example of using a consultative method. This approach does not involve actively engaging with the customer or considering their individual needs and preferences.
