Hi, can someone help me with this please.

PPFZ D X A change in technology causes the production possibility frontier for this country to move from PPF1 to PPFZ. Based on this graph, identify whether each of the following would be true or false and briey explain your reasoning. A. After the change in technology, bundles "A\" and "B" would both be efcient in production. B. As a result of the change in technology, the opportunity cost of producing good X will increase and the opportunity cost of producing good Ywill decrease relative to before the change in technology. C. If this country was initially producing bundle \"C\" on PPF1, the technology change will allow this country to increase its production of both goods relative to what it was initially producing prior to the change in technology. D. Both PPFl and PPF2 are downward sloping. This indicates that the marginal cost of producing good X decreases as more of good X is produced
