The key characteristics of unstructured data are:

1. Unorganized: Unstructured data is not organized in a pre-defined manner or does not follow a specific format. It is usually stored in its raw format.

2. May have an internal structure: While unstructured data is not organized in a traditional database format, it may still have an internal structure. For example, a Word document has an internal structure that is understandable by the Word software, but this structure does not lend itself to processing and analysis in the same way that structured data does.

The other options, "Clearly identifiable construction" and "Fits neatly into rows and columns", are not characteristics of unstructured data. These are typically characteristics of structured data. Structured data is highly organized and easily searchable in relational databases, where it is stored in rows and columns.
