What happens to the file size after running gzip -9 file.log compared to gzip -1 file.log?

AThe file size increases with -9

BThe file compressed with -9 is smaller than with -1

CBoth produce the same file size

DThe file compressed with -1 is smaller than with -9

Step-by-Step Solution

Solution:

Step 1: Understand gzip compression levels
-1 is fastest with less compression; -9 is slowest with maximum compression.
Step 2: Effect on file size
Higher compression level (-9) produces smaller files than lower level (-1).
Final Answer:
The file compressed with -9 is smaller than with -1 -> Option B
Quick Check:
Higher gzip level means smaller file = D [OK]

Quick Trick: Use -9 for best compression, smaller files [OK]
