The most direct effect of the trend shown in the graph is the electronic linking of people around the world. Hence, Option D is correct.
What is electronic linking?
A link is the connection between two people, things, or ideas. For example, there's a direct link between diet and heart disease; their links with Mexico are still strong; and many more.

Therefore, Option D is not correct.
