Final answer:
The RGB setting for pure blue color is option d). 0000 0000 0000 0000 1111 1111, which indicates that only the blue channel is fully turned on, and the red and green channels are off.
Step-by-step explanation:
In RGB settings, blue is represented by turning on the blue component fully while keeping the red and green components turned off.
Therefore, the correct RGB setting for blue, where 0 is off and 1 is on, is represented as: d). 0000 0000 0000 0000 1111 1111
This setting means that the blue channel is set to its maximum value, whereas the red and green channels are set to zero, resulting in the color blue being displayed.
In terms of theory, when light hits an object, the object's color is determined by the wavelengths of light that are absorbed and reflected. A pure blue object would absorb all light except for blue light, which it would reflect, thus appearing blue to the observer.
