The command that will reduce all consecutive spaces down to a single space is:
E. `tr -s ' ' < a.txt > b.txt`
The `-s` option in the `tr` command squeezes (or reduces) consecutive spaces into a single space, effectively eliminating duplicate spaces in the input file `a.txt` and saving the result to `b.txt`.
