Answer:
C. Full employment, fixed supplies of resources, fixed technology, and two goods
Explanation:
Production Possibility curve: It is a curve that shows all possible combinations to the amounts of the two goods that can be produced with the available resources and technology. 
In simple words, all resources which are used to produce the possible combinations are called full employment. Thus, these specific assumptions plays vital role in production possibilities curve. 
So, A, B, and the D are incorrect options. 
 
        
             
        
        
        
The total cost that is incurred by producing 100 doughnuts is equal to the sum of the variable cost and the fixed cost. The total variable cost is,
    total variable cost = ($2/doughnut)(100 doughnuts) = $200
The total cost is,
   Total cost = total variable cost + total fixed cost
     TC = $200 + $500 = $700
Equating the cost and the revenue,
     TC = TR
     $700 = (100)(x)
The value of x from the equation is $7.
