Answer: Option D
Explanation: A grid's primary purpose – at a minimum in product design – is to create a set of instructions about how to arrange items within a format. An efficient system not only provides the pattern for a system but specifies the meter as well.
This is an effective way of making the material available and letting the user recognize how the next bit of information can be found inside the design.
It fosters creativity and determines the design principles, intonation, and speech in some instances. Consider of a grid as when the route map the visitors are driving through.
