Explanation
The maximum price of $300,000 is a constraint that the solution must be bound to. The solution does not have to cost $300,000, it just cannot exceed this limit.
Answer A is incorrect. A budget is the defined amount of funds to implement a solution. In this instance, the
stakeholder will accept a maximum of $300,000 or less for a solution. Because a solution has not been identified the budget is not yet known.
Answer D is incorrect. Requirements are the characteristics of the solution, not the constraint of the price.
Answer C is incorrect. A solution has not yet been proposed so the cost of the solution is still unknown.
