(Figure: Savannah's Production Possibilities) Use Figure: Savannah's Production Possibilities. Which point or points represent(s) an inefficient combination of bananas and pineapples? A graph plots Quantity of bananas on the vertical axis versus Quantity of pineapples on the horizontal axis and shows a curve. The horizontal axis ranges from 0 to 50, in increments of 10. The vertical axis ranges from 0 to 35, in increments of 5. The curve is concave down and decreases from (0, 30) to (40, 0). Points A and B are plotted at (20, 25) and (30, 20), respectively. Two more points, C and D, are plotted at (20, 20) and (40, 30), respectively. Question 3 options: a) A only b) A and B c) B and D d) C only
