A user reports they cannot read a file in a shared directory, even though the file permissions are 644 and the user is a member of the group that owns the file. What is the most likely reason?

The file is owned by root and the user is not root.

The file has the SUID bit set, which prevents reading.

The directory permissions do not allow the user to traverse to the file.

The user is not the owner and the group permissions do not apply because the user is not in the group.
