Which term describes the size of each pixel in an image?

Pixel dimension Resolution Color depth Aspect ratio

Correct Answer:

Pixel dimension

Explanation:

Pixel dimension is the number that specifies how many pixels make up the image in width and height, i.e., the image’s size in pixel units. Saying an image is 1920 by 1080 tells you there are 1920 pixels across and 1080 pixels down, which is exactly what describes its size in pixels. Resolution is related but can be broader, sometimes signaling detail or display density rather than the exact pixel grid. Color depth refers to how many bits are used to represent each pixel’s color, not how many pixels there are. Aspect ratio is about the proportional relationship between width and height, not the pixel count.
