Which Sublist3r option is used to write results to a file?

• A. -d DOMAIN
• B. -t THREADS
• C. -e ENGINES
• D. -o OUTPUT

Answer: (D)

The ability to save results to a file in Sublist3r is provided by the -o option, which takes a file path after it (for example, -o output.txt). This flag directs Sublist3r to write the discovered subdomains to that file instead of printing them to the screen. The other flags configure what to search or how the search runs: -d sets the domain to target, -t controls the number of threads used, and -e selects which engines to use. These don’t specify a file for output, so they don’t save results by themselves. So the -o OUTPUT option is the correct one for writing results to a file.
