reduces quality
A
lossy compression
B
lossless compression
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -After compression, lossy files are smaller in size than lossless ones. However, the quality is usually lower than it would be if you’d used lossless compression. That said, it may not be too noticeable, depending on how you are viewing the image and the type of image it is.

Detailed explanation-2: -Lossless compression means that you reduce the size of an image without any quality loss. Usually, this is achieved by removing unnecessary metadata from JPEG and PNG files.

Detailed explanation-3: -One of the biggest obvious benefits to using lossy compression is that it results in a significantly reduced file size (smaller than lossless compression method), but it also means there is quality loss.
