Zoom lenses can potentially distort images primarily by making straight lines appear curved. This effect is often associated with certain types of zoom lenses, especially those with a large zoom range or particular focal lengths, leading to issues like barrel distortion or pincushion distortion. These distortions can affect the overall composition and clarity of the image, altering the perception of subjects within the frame.
The other options provided don't generally characterize the distortion caused by zoom lenses specifically.
