The data blocks of a very large file in the unix file system are allocated using an extension of indexed allocation or EXT2 file system. Hence, option (D) is the right answer.

Yes. But UFS and EXT2 are not the same. EXT2 is used in Linux but UFS existed even before.

(You can consider Unix as a base class and Linux and MAC its two derived classes)
