A pixel, short for "picture element," is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device. Pixels are the building blocks of digital images, and each pixel typically represents a single point in the image. When combined, these pixels create the overall image that can be viewed.

In digital images, pixels are represented in a grid format, with each pixel having a specified color and intensity. This allows for the representation of complex images through combinations of pixels.

The correct understanding of pixel concerning its options involves recognizing that it pertains specifically to a "digital image." Therefore, the best response aligning with the definition of a pixel would be "elements of a digital image."

In contrast, an analog image does not use discrete pixels but rather varies continuously in terms of color and intensity. Hence, terms like "cluster of a digital image" or "cluster of an analog image" do not accurately describe the fundamental nature of a pixel.
