Which of the following would best enable a marketer to measure the utility a customer attaches to a new product's features?

A) Kano model
B) SWOT analysis
C) conjoint analysis
D) virtual reality test

Conjoint analysis is a research method used to determine how customers value different features of a product or service. It asks customers to make trade-offs between different product attributes and helps to determine their preferences and willingness to pay for each attribute. The Kano model is used to determine which product features are essential to customer satisfaction, while a SWOT analysis focuses on a company's strengths, weaknesses, opportunities, and threats. A virtual reality test may provide insights but is not specifically designed to measure customer utility for different product features.
