What use can a border made of lines have in a poster?

To make the composition look organized and bounded

A line border gives a poster a clear outer limit and helps organize the space inside it. It can separate the design from the empty area around the paper, make the poster look complete, and guide the viewer’s eyes toward the central message or image. The border may be simple or decorative, but its basic visual function is to create structure and a sense of order.

Choice A is correct because a border defines and organizes the composition. When the artist places a line around the edges, the words, pictures, and empty spaces inside can appear connected as one planned design. Choice B is incorrect because a border does not erase the message. Choices C and D are unrelated to the visual purpose of a line. A border can sometimes attract attention, but it should not be so strong that it competes with the main message. Therefore, its useful role is to make the poster look organized and bounded.
