The correct answer is A. Tape drive. Tape drives are sequential access devices that require physically winding the tape to locate data, resulting in significantly longer seek times compared to random-access storage like hard drives or solid-state drives.

Why each option

Tape drives are sequential access devices that require physically winding the tape to locate data, resulting in significantly longer seek times compared to random-access storage like hard drives or solid-state drives.

ATape driveCorrect

Tape drives store data sequentially, meaning that to access a specific piece of data, the drive must wind the tape to the correct position. This physical movement makes tape drives inherently have the longest seek times compared to other storage media options listed, which are random-access devices.

BSolid-state drive

Solid-state drives (SSDs) have no moving parts and offer extremely fast seek times, making them the fastest option for data access, completely contrary to the scenario.

CRemovable drive

Removable drives are a broad category; while some removable drives might be slower, many are USB hard drives or SSDs, which still offer significantly faster seek times than tape.

DHard drive

Hard drives (HDDs) use spinning platters and read/write heads for data access. While they have mechanical seek times, these are orders of magnitude faster than the time it takes to wind a tape to a specific location.
