A Correct answer
Explanation

The find command recursively locates all files (type f) starting from the current directory, and grep -l searches within each file's content for the string 'file', outputting only filenames that contain a match. Option B incorrectly searches filenames rather than contents, while options C and D only examine the current directory without recursion.
