c. growth in the economy shifts the ppc left.
d. an economy is efficient if it maximizes utilization of all the available scarce resources.

Statement D is false.

An economy is not efficient if it maximizes the use of all the scarce resources available, since by maximizing the use of a scarce resource, it will end and production will suffer due to lack of certain inputs. In short, before a scarce resource one should try to boost the quantity of the scarce product to raise its quantity, and thus be able to produce normally.
