Aroha enjoys walking to the beach and photographing the sunset. When she downloads the images to her computer, she saves two different versions. She keeps one version with the full amount of pixels, so that she can use the images for any project in the future. In the second version, she reduces the number of pixels by half. What would be a benefit of reducing the number of pixels?
a. less storage space taken up
b. better quality
c. better for creating large posters
d. less boxy-looking
