Select the smallest memory size:

The correct answer is B. Kilobyte.

A kilobyte is a unit of information or computer storage equal to 1,024 bytes. A byte is a unit of digital information that most commonly consists of eight bits. A bit is the smallest increment of data on a computer.

A kilobyte is a relatively small amount of storage. For example, a typical email message might be 1 kilobyte in size. A song file might be 10 megabytes in size. A high-definition movie file might be 1 gigabyte in size.

The other options are larger units of storage. A megabyte is equal to 1,024 kilobytes. A gigabyte is equal to 1,024 megabytes. A terabyte is equal to 1,024 gigabytes.
