Which of the following is the smallest memory unit in the given options?

The correct answer is (c) Kilo Byte.
Explanation:
● Among the given units, Kilobyte is the smallest storage unit.
● 1 KB = 1024 Bytes, which is lower than MB, GB and PB.
● Higher units represent much larger storage capacity, increasing in multiples of 1024.
Information Booster:

● 1 MB = 1024 KB.

● 1 GB = 1024 MB.

● 1 PB = 1024 TB.

● Storage increases from KB → MB → GB → TB → PB.

● Computer memory is measured in binary multiples.
Additional Information:

● (a) Peta Byte – Very large storage unit; used in data centers.

● (b) Giga Byte – Used in mobile/PC storage; larger than MB.

● (d) Mega Byte – Used for document/file size; larger than KB.
