      3. Final Answer:

        aws --version -> Option B

      4. Quick Check:

        This error means the system cannot find the program to run it.

      2. Step 2: Identify common cause

        Usually, the AWS CLI executable is not in the system PATH, so the terminal can't locate it.

      3. Final Answer:

        AWS CLI is not added to your system PATH environment variable -> Option A

      4. Quick Check:

        Command not found = PATH missing [OK]
      Hint: Add AWS CLI to PATH to fix 'command not found' error [OK]
      Common Mistakes:
      • Assuming internet is needed to run version command
      • Thinking password is required to run CLI
