For each pair of jeans Casina produces, it gives up to opportunity to make 50 pounds of chocolate truffle. Marina can produce one pair of jeans for every 100 pounds chocolate truffle it produces. Suppose the data is converted into production possibilities frontiers(PPF) with constant opportunity costs for both countries . While the pound of chocolate truffle produced are measured on the vertical axis. Identify the correct statement in this case: a- The slope of Marina's production possibilities frontier is equal -50
b- The slope of MArina's production possibilities frontier is flatter than Casina's
c- The slope od MArina's production possibilities frontier is equal to -0.02
d- The slope of Marina's production possibilities frontier is equal to -0.01
