C Correct answer
Explanation

The tail command displays the last lines of a file. Using tail -n 15 dog cat horse will show the last 15 lines of all three files (dog, cat, and horse). The head command shows the beginning of files, not the end. While tail -15 works as an older syntax, tail -n 15 is the more explicit and preferred form.
