Suppose we have variable logical records of lengths of 55 bytes, 1010 bytes and 2525 bytes while the physical block size in disk is 1515 bytes. What is the maximum and minimum fragmentation seen in bytes?

  1. 2525 and 55
  2. 1515 and 55
  3. 1515 and 00
  4. 1010 and 5

what is the answer c or D?

i guess it should be C. Here they haven't mentioned that we have  2 blocks. All those who is supporting answer D uses 2 blocks. 

Some please give the concrete solution.
