From the instantaneous response that Natalie experienced, the answer should be C) Sensation.
In any business, when the cost of resources rise, the price of buying the commodity will also be high, this is because when it cost you much to produce a commodity, you will end up charging a higher price when selling it. Failure to do so may lead to making loses. The opposite is also true, when the cost of resources fall, the pricing will also be less.
The correct answer to this open question is the following.
The business decision based on the company where you work would be this. To open a new small branch of the fast-food restaurant as a concession in the municipal stadium.
The incremental cost is the future costs as a result of this business decision. This means that we have to consider extra money on a monthly basis to pay for the rent of the concession booth at the Municipal stadium.
The opportunity cost is that instead of opening our branch in the new downtown mall, we decided to move with the stadium option. Having decided to be at the mall could have allowed us to have more clients on a daily basis, especially on weekends.
The sunk cost is a cost from the past, an historical cost that really is not important in the present time to make a decision. Maybe, just a reference to a case in the past. And that's it.
Here we can refer to a cost when we opened the first location of the restaurant, but it was five years ago. Those were different situations, necessities, and conditions.
