A Correct answer

Hard disk storage capacity equals the product of tracks, sectors, bytes per sector, and read/write heads. Each head accesses one surface (platter side), so the total capacity must account for all surfaces. Option B misses the heads multiplier entirely, while D misses both heads and bytes per sector.
