Question: How many disk accesses are needed to bring byte i of a file into memory when the file is stored using double indirect indexed allocation

How many disk accesses are needed to bring byte i of a file into memory when the file is stored using double indirect indexed allocation? Assume only the file's FCB is in memory , block pointers require 32 bits , and that blocks hold 4096 bytes each.

1 + [i/4096] accesses
i accesses
2 accesses
2 + [i/4096] accesses
3 accesses
1 access
[i /4092] accesses
2 + [i/4092] accesses
