I disagree, I believe the correct answer is A) tr '\s' ' ' < a.txt > b.txt because it replaces all occurrences of whitespace characters with a single space.

I think the answer is E) tr -s ' ' < a.txt > b.txt because the -s option squeezes multiple occurrences of the specified character into a single occurrence.
