Final answer:
The Bicubic Resampling method should be used when resampling an image in the Image Size dialog box to enable the Reduce Noise slider.
Step-by-step explanation:
The resampling method that should be used when resampling an image in the Image Size dialog box to enable the Reduce Noise slider is Bicubic Resampling.
When you increase or decrease the size of an image using the Image Size dialog in software like Photoshop, you will often need to resample the image. Resampling is the process of changing the number of pixels in the image, which can result in a loss of detail or clarity.
The Bicubic Resampling method uses a more advanced algorithm compared to other methods, resulting in better quality when resizing an image. This method takes into account the surrounding pixels and their colors to determine the best color for each pixel, which helps to reduce noise and artifacts in the image.
