Answer:
B) outward shift of the PPF.
Step-by-step explanation:
The production possibilities frontier (PPF) refers to the different combinations of production output for two different goods that can be produced given a fixed amount of available resources (e.g. machinery, materials, labor).
If there is an increase in the availability of resources (e.g. more materials are available or more machines are used), then more goods can be produced. Therefore the PPF curve should shift outwards since total output will increase.
