​

Answer 1

Explanation:

Row data block is the table entry that contains the block number of next block. It stores the information related to block indexing. This forms chain where the block numbers of the next blocks are stored. This chain also contains the information about the last block which is determined by end-of-file value. Advantage of this is that it reduces disk access time
