Which is the largest unit of storage among the following?

A terabyte is the largest here, equal to about 1024 gigabytes.

A megabyte is roughly a million bytes, far smaller than a terabyte.

A kilobyte is about a thousand bytes, the smallest listed.

A gigabyte is about 1024 megabytes, still below a terabyte.

The order rising in size is kilobyte, megabyte, gigabyte, terabyte.

Beyond a terabyte comes the petabyte, again a thousand times larger.
