Suppose that you have a UNIX file system where the disk block size is 4096 bytes. Disk addresses and file block pointers take 32 bits (4 bytes), and the i-node contains 12 direct pointers, one single-indirect pointer and one double-indirect pointer. Assume an index block is the same size as a data block, then the maximum number of data blocks a file will support by this i-node is

Question
Could I please get some step by step guidance on how to solve this OS question regarding i-nodes?
Suppose that you have a UNIX file system where the disk block size is 4096 bytes. Disk
addresses and file block pointers take 32 bits (4 bytes), and the i-node contains 12 direct
pointers, one single-indirect pointer and one double-indirect pointer. Assume an index block is
the same size as a data block, then the maximum number of data blocks a file will support by
this i-node is
a. 12 + 1024 + 1024² + 10243
b. 12 + 1024 + 1024²
c. 12 + 4096 + 4096²
O d. 12 + 1024
e. 12
