Which description best matches the meaning of the NTSC 4:3 aspect ratio?

Explanation:
The main idea here is describing the shape of the image frame. NTSC 4:3 is an aspect ratio, which gives the width-to-height proportion of the picture. The “4:3” means four units wide for every three units tall, defining a frame that is more square-ish than a widescreen shape. This is about the frame’s shape, not how many frames are shown per second or how many colors can be represented. So, the correct concept is the width-to-height relationship. The other ideas refer to motion rate (frames per second) or color depth, or mix terms that don’t describe the frame’s shape.
