Answer:
The right approach is Option d (Sales commissions).
Explanation:
- Sales commission seems to be an expense for the time that is not reflected throughout inventory commodity prices. That would be the amount that could be received by a sales agent as well as a sales representative including its price of a property.
- The cost of products generated, credit card payments, postage charges the sales commission that you will allocate to sales workers are including variable costs.
Some other three choices are not associated with the case in question. So, option d seems to be the right choice.
