The correct option is A) 1024 Gigabytes.

– In computer memory measurement, units are typically based on powers of 1024 (2^10), which is related to the binary nature of digital systems.
– The standard progression of units is:
– 1 Kilobyte (KB) = 1024 Bytes
– 1 Megabyte (MB) = 1024 Kilobytes
– 1 Gigabyte (GB) = 1024 Megabytes
– 1 Terabyte (TB) = 1024 Gigabytes
– 1 Petabyte (PB) = 1024 Terabytes

– Storage manufacturers sometimes use decimal prefixes (powers of 1000) for marketing capacity (e.g., 1 GB = 1000 MB), but for internal computer architecture and operating system reporting, binary prefixes (powers of 1024) are conventionally used unless otherwise specified (e.g., Kibibyte, Mebibyte, Gibibyte, Tebibyte). In general knowledge questions like this, the 1024 basis is usually implied for TB, GB, MB, KB conversions.
