Is it possible to distinguish a file from a hard link to a file? That is, given a filename, can you tell whether it was created using an ln command? Explain.
a. Yes, because a hard link and a file have different inode numbers.
b. No, because both a file and a hard link share the same inode number.
c. Yes, because a file and a hard link have different timestamps.
d. No, because the ln command does not create distinguishable attributes between a file and a hard link.
