Indexed file allocation:
In Indexed file allocation, If a file requires n blocks then n+1 blocks are used where the first block contains index information(pointers to data blocks).
  • The Indexed file allocation table contains a separate one-level index for each file.
  • The index has one entry for each portion allocated to the file.
  • The file allocation table contains the block number for the index.
Hence the correct answer is Indexed file allocation.
