The correct answer is B. resolution.
Plotter accuracy is measured in terms of repeatability and resolution. Repeatability is the ability of the plotter to reproduce the same output multiple times, while resolution is the ability of the plotter to produce fine detail.
Buffer size is the amount of memory that the plotter has to store data before it is sent to the printer. This is not directly related to accuracy.
Vertical dimension is the height of the plotter’s paper path. This is not directly related to accuracy.
Intelligence is a measure of the plotter’s ability to understand and respond to commands. This is not directly related to accuracy.
Therefore, the correct answer is B. resolution.
