Answer:

a. modern disks do not disclose the physical location of logical blocks.

Explanation:

In modern disks, the disk scheduling algorithms are built in the disk drive. It is difficult for operating system to schedule for improved rotational latency. All scheduling algorithms are forced to behave the same because operating system may have constraints. Disks are usually accessed in physical blocks. Modern disks put more electronic controls on the disk.
