D.) Various colors depending on their size.

I think it is D.

Thank You.

## Actually, the correct answer is C.) A land area of 30 by 30 meters.

In computer graphics and imaging, a pixel is the smallest unit of a digital image or display. It is a tiny square or dot that can be assigned a specific color or grayscale value. When referring to a satellite image or digital map, one pixel typically represents a certain area on the ground.

To determine the answer to this question, we need to understand the concept of pixel resolution. Pixel resolution refers to the number of pixels per unit of area or length. In this case, the question is specifically asking about the representation of a single pixel.

Each pixel in a satellite image or digital map corresponds to a specific area on the ground. The size of this area is determined by the pixel resolution. For example, if the pixel resolution is 30 by 30 meters, it means that each pixel represents a land area measuring 30 meters wide and 30 meters high.

Therefore, the correct answer is C.) A land area of 30 by 30 meters.
