-How is slope, measured as rise over run, related to the production possibilities frontier?

A) Slope measures the fixed costs of producing Good X and Good Y. For a slope of -3, the fixed cost of producing either Good X or Good Y is $3 multiplied by the number of units produced.
B) Slope gives the opportunity cost of producing an additional unit of the good on the x-axis. So, if the slope is -3, the country must give up producing one-third of a unit of Good Y for every additional unit of Good X it produces.
C) Slope gives the fixed cost of producing an additional unit of the good on the x-axis. So, if the slope is -3, the country must give up producing one-third of a unit of Good Y for every additional unit of Good X it produces.
D) Slope gives the opportunity cost of producing an additional unit of the good on the x-axis. So, if the slope is -3, the country must give up producing 3 units of Good Y for every additional unit of Good X it produces.
