Show answer & explanation
Correct answer: C
Comparing storage capacities given in different units (KB, MB, GB, TB) requires first converting every value into a single common unit. Moving up the storage-unit ladder — KB to MB to GB to TB — is always a multiplication by 1024, since these are binary prefixes, not decimal ones.
Device (as given) | Capacity in GB |
|---|---|
16 GB Pen Drive | 16 GB |
1024 KB Pen Drive | ≈ 0.001 GB |
1 TB External Hard Disk | 1024 GB |
512 MB External Hard Disk | 0.5 GB |
Cross-check using a different common unit (megabytes): 16 GB = 16,384 MB; 1024 KB = 1 MB; 1 TB = 1,048,576 MB; 512 MB = 512 MB. The ranking stays the same no matter which common unit is used.
The 1 TB External Hard Disk, equal to 1024 GB, holds far more data than any of the other listed devices, making it the option with the highest storage capacity.
