This can help to improve the quality of the image as it eliminates any unwanted noise caused by these rays. Options A, B, and D do not accurately describe the purpose of an aluminum filter. Enhancing image contrast, eliminating scatter radiation, and controlling exposure time can all be achieved through other means and are not the primary purpose of an aluminum filter.
