Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Appending & before a command runs it in the background, allowing the command to execute asynchronously while returning you to the command prompt immediately. The shell does not wait for the command to complete. Option A is incorrect because no error occurs. Option C is incorrect because & does not enable multiple input processing. Option D is incorrect because the syntax is valid.
