Which option preserves aspect ratio when resizing an image?

• A. Constrain image proportions
• B. Pixel aspect ratio
• C. Interpolation
• D. Crop

Answer: (A)

Preserving aspect ratio means scaling the width and height together so the image’s shape stays the same, avoiding stretching or squashing. The option that keeps those dimensions linked is the one that constrains image proportions. When this is active, changing either width or height automatically adjusts the other to maintain the original ratio, so the image scales evenly. Pixel aspect ratio is about the shape of individual pixels rather than how the whole image scales. Interpolation determines how new pixels are calculated during resizing and affects quality, not the proportional relationship. Cropping trims parts of the image and changes composition, not how the image scales proportionally.
