The marketing department has just discovered that most buyers are not willing to pay the extra cost of one of the features planned in your current?

I am not sure what you mean with your current ....

 But option D would be a my answer .........since no buyer is willing to pay for additional tests, even if means it will inhance the product

The goal of EVC (economic value to the customer) is to quantify the additional value a product brings to customers above what they already receive from their present suppliers. The main principle of EVC is that for any customer currently using the reference product, there are two possible ways of benefiting from switching over to yours. First, your product may have better functionality; it may simply do its job better or faster. In the business-to-business context, functionality often means that your product enables the customer to charge its own customers higher prices, to work more efficiently, or to earn more profit in some other way.

Second, your product might outstrip the reference product by placing lower burdens on the customer. Especially if you are focusing on business equipment, the reference product might require its buyer to incur certain start-up or postpurchase costs. By "start-up costs," we mean such things as insurance, installation, and employee training. By "postpurchase costs," we mean maintenance, data entry, ongoing employee training, and so on.
