Explanation

'awk' is a powerful text-processing tool designed specifically for working with structured, field-delimited data. It can split records by a custom delimiter (e.g., awk -F',' '{print $2, $4}' file.csv) to extract and print specific columns from a CSV file. 'sort' reorders lines but does not extract fields. 'print' is not a standard standalone Linux command for this purpose. 'echo' outputs text strings but cannot parse or extract fields from a file. awk is the correct and idiomatic tool for this field-extraction task.
