Where Inode Fifty One Lives

A vsfs volume uses 4 KB blocks and 256-byte inodes, laid out like this:

vsfs layout: block 0 superblock, block 1 inode bitmap, block 2 data bitmap, blocks 3 to 7 inode table, blocks 8 to 63 data S i-bmap d-bmap I I I I I data blocks 0 1 2 3 4 5 6 7 8 to 63 inode table starts at byte 12288 (12 KB)

Sectors are 512 bytes. Which absolute block holds inode 51, and what is the sector number where that block begins?

A

block 54, starting at sector 432

B

block 6, starting at sector 48

C

block 7, starting at sector 56

D

block 3, starting at sector 24
