BThe command should use a single > instead of >>
CThe echo command does not support redirection

Step-by-Step Solution
Solution:

  1. Step 1: Analyze the command

    echo "Sample" >> ends with the append operator but no filename.

    Redirection operators require a target file; missing filename causes syntax error.

    The redirection operator is incomplete without a filename -> Option D

Quick Trick: Redirection operators must be followed by a filename [OK]
Common Mistakes:
  • Omitting filename after >>
