In this question about short run vs long run in economics, we need to unpack what each time frame allows for inputs.
Option A: 'the quantities of all factors of production are fixed; the quantities of all factors of production can be varied' mixes up the two time frames. If all factors were fixed, there would be no adjustment period at all, which describes neither the short run nor the long run as typically defined. This makes A incorrect.
Option B: 'the quantities of some factors of production are variable; the quantities of all factors of production are fixed' would imply that nothing can change in the long run, which contradicts the idea that in the long run all inputs are adjustable. Therefore B is not accurate.
Option C: 'the quantities of all factors of production are variable but technology is fixed; sunk costs are variable' introduces a problematic distinction. In standard theory, the short run assumes some factors are fixed (not all), and there is no blanket assumption that technology is fixed for the entire short run while all factors are variable. This wording is inconsistent with the typical short-run/long-run framework and adds extraneous conditions about sunk costs, making C incorrect.
Option D: 'the quantities of some factors of production are fixed; the quantities of all factors of production can be varied' aligns with the conventional definitions. In the short run, at least one input is fixed, allowing limited adjustments; in the long run, all inputs can be varied, permitting full adjustments. This option captures the core distinction between the two time horizons.
To sum up, each option is evaluated against the standard economic distinction between short run and long run, and only D coherently expresses that some inputs are fixed in the short run while all inputs are variable in the long run.
