What does this shell pipeline print?

printf "3\n10\n2\n" | sort | head -1
  1. 2
  2. 3
  3. An error, because sort needs the -n option for numbers
  4. 10
Answer and explanation

Answer: D. 10

Explanation: Without -n, sort compares lines as text, character by character. '1' sorts before '2' and '3', so 10 comes first. sort -n would put 2 first.
