Alignment.
Answer: Option D.
Explanation:
The principle of alignment means that when we align ideas, we are putting different ideas together. These ideas which are put together have an invisible connection among themselves.
When we align elements that go together with each other, there is an organisation within the structure that makes the design and the work flow smoothly without any irruptions. It is very important to know what and why the different pieces needed to be aligned together and in what way are they to be organised.
