Final answer:
Option 3, which asks if the concept aligns with customer needs and preferences, is the question most likely to be asked during concept testing.
Step-by-step explanation:
When conducting concept testing with customers, the goal is to understand how they perceive a new product or service concept and if it aligns with their needs and preferences. Hence, among the provided options, the question that is likely to be asked during concept testing is Option 3: "Does the concept align with your needs and preferences?" This question is designed to gauge whether the concept would be appealing and useful from the customer's perspective and if there is potential for market success.
Questions about development costs, favorite colors, or current exchange rates for the Euro to the US Dollar are not directly related to understanding customer needs during the concept testing phase and are therefore less likely to be part of the concept testing process.
