Show answer & explanation
Correct answer: C
To calculate the maximum capacity, multiply cylinders by tracks per cylinder, sectors per track, and bytes per sector: 100 × 10 × 10 × 128 = 1,280,000 bytes. Convert to kilobytes using the binary definition (1 KB = 1024 bytes): 1,280,000 / 1024 = 1250 KB.
