Final Answer:
A pixel on a phone screen is typically modeled by a square (Option C).
Step-by-step explanation:
Nature of Pixel Representation:
In digital displays, including phone screens, images are formed using a grid of pixels. Each pixel is a discrete unit that represents the smallest element of an image.
Pixel Shape (Option C):
A pixel is commonly represented by a square shape on digital screens. In most cases, pixels are arranged in a grid, and each pixel is a small square that combines with others to form images.
Alternative Shapes:
While some advanced displays may use non-square pixel shapes for specific purposes, the standard representation for pixels, especially on phone screens, is a square.
Therefore, the accurate geometric shape modeled by a pixel on a phone screen is a square.
Option C is the answer.
