Which option changes the number of pixels in the image?

• A. Image Size Change
• B. Cropping
• C. Scaling
• D. Resampling

Answer: (D)

Changing the number of pixels in an image means altering how many data points make up the picture, which happens when you resample. Resampling adjusts the image’s pixel grid by adding new pixels when you enlarge or removing pixels when you shrink, usually using interpolation to estimate colors. Cropping changes what portion of the image is kept, and often is treated as altering the visible area without changing the underlying pixel data in a way that renumbers the entire image’s grid. Scaling by itself changes how big the image appears, but without resampling you’re not changing the actual pixel count stored in the file. Therefore, the operation that truly changes how many pixels the image contains is resampling.
