Show answer & explanation
Correct answer: A
Answer: The aspect ratio is the ratio of the width (length) of the screen to its height.
Explanation: Aspect ratio describes the proportional relationship between the horizontal and vertical dimensions of a display. It is written as width:height (for example 16:9 or 4:3). It indicates shape, not the physical size of the screen.
How to read it: 16:9 means the width is 16 units for every 9 units of height.
Common examples: 16:9 (widescreen), 4:3 (traditional TV/monitor).
Why the other descriptions are incorrect:
A definition that uses height divided by the sum of length and height is incorrect because aspect ratio is a direct comparison between two dimensions, not a fraction involving their sum.
Definitions that describe screen brightness or color composition are talking about display settings, not aspect ratio, so they are not relevant.
