The correct answer is: B. Plots must be created on a graphics device.
A plot is a graphical representation of data. It can be created on a graphics device, such as a computer screen or a printer. However, it can also be created on a file device, such as a hard drive or a USB drive. This allows the plot to be included in other documents or sent to other people.
For file devices, there are two main types of formats: vector and bitmap. Vector formats store data about the lines and shapes in a plot, while bitmap formats store data about the individual pixels in a plot. Vector formats are typically used for plots that need to be scaled or printed at different sizes, while bitmap formats are typically used for plots that need to be displayed on a screen.
In conclusion, the statement “Plots must be created on a graphics device” is wrong. Plots can also be created on a file device.
