A. A productive process cannot be technologically efficient unless it is economically efficient.
B. A technologically efficient production process uses the least amount of nonrenewable resources per unit of output.
C. An economically efficient production process must be technologically efficient.
参考答案：C
解析：
For a process to have the lowest production cost (be economically efficient it must be techno logically efficient. A process is technologically efficient if there is no other process that can produce the same output with less of at least one input and no more of the other inputs. A process that uses no less of any input and more of at least one input cannot be the lowest cost process and is, by definition, not technologically efficient.
