You need-afor hidden files,-lfor detailed info,-hfor human-readable sizes, and-Rfor recursive listing.Step 2: Combine options correctly

B (ls -lha) misses recursive-R. C (ls -aRl) includes all options but order does not matter in Linux, so it is also correct. D (ls -l -a -h) misses recursive-R.Final Answer:
ls -alhR -> Option AQuick Check:
All needed options combined =ls -alhR[OK]
