A disk scheduling is done by the operating system and is made fir the rescheduling the input and output of the disk. Several algorithms includes FCFS, SSTF, SCAN scheduling, C-SCAN , LOOK , C-LOOK. Multiple input and output requests can be used for arriving at different processes and only one request can be served at a time. Hard drives are the slowest parts of the system. The modern disks don't disclose location of any logical blocks. Hence the option A is correct. Learn ore about the algorithms in operating systems consider only. brainly.in/question/9248259
