Answer is (A). Larger block size means less number of blocks to fetch and hence better throughput. But larger block size also means space is wasted when only small size is required.

ans is a 

If block size is large then seek time is less (fewer blocks to seek) and disk performance is improved, but remember larger block size also causes waste of disk space.

So option a is correct.

D.

Using larger block size makes disk utilization poorer as more space would be wasted for small data in a block. It may make throughput poor as the number of blocks would decrease.
