Should be B.

nope its “A”
“The amount of time that a disk drive’s head takes to move to a specific location on a disk” is the definition of seek time

nope it’s B, rotational delay is the time it takes the platter to do a full rotation back to the r/w head, seek time is the time it takes to move the r/w head to the correct sector.

Documentation
the actuator arm moves the R/W head over the platter to a particular track while
the platter spins to position the requested sector under the R/W head.
The time taken by the platter to rotate and position the data under the R/W head is called rotational latency
The seek time (also called access time) describes the time taken to position the R/W heads across the platter with a radial movement (moving along the radius of the platter).
In other words, it is the time taken to position and settle the arm and the head over the correct track.

It’s A. 100% – A
Seek time – describes the time taken to position the r\w heads accross the platter with a radial movement.
Rotational delay – time taken by the platter to rotate and position the data under r\w head

move heads = seek time
move platter = rotational delay
Should be B.

TLDR
Key word — Sector & Platter = Rotational delay (Latency)
(NOT TRACK & PLATTER = Seek Time)
