Answer:
The correct answer is letter "D": Value proposition.
Explanation:

The purpose of the value proposition of the business is to convey a reason for the consumer to buy from the business and to direct the company in making decisions that are consistent with this promise.
A concise value proposition will identify who the main customers are, what the problems of the customers are, what unique benefit the products of the company provide, and why this benefit is better for the customers than the advantages of the competitors.
