I had been asked this question by my college professor while I was bunking the class.

I would like to ask this question from Listing File and Directory Attributes in section Basic File Attributes of Unix

Answer 1

The correct choice is (c) 2048

Explanation: Sine files are written to the disk in terms of block size, the size consumed by the file vary from the original size of the file. Suppose, if a file size is 800 bytes but the block size on the system is 1024 bytes, then that file will consume 1024 bytes on diskspace i.e. 1 block.
