The correct answer is: D.Complex.

Prokaryotic cells are generally simple in structure, not complex. They lack membrane-bound organelles and a nucleus, and their DNA is typically found in a single circular chromosome located in a region called the nucleoid, not in a membrane-enclosed nucleus. This makes prokaryotes simpler compared to eukaryotic cells, which have more complex structures with specialized organelles (such as a nucleus, mitochondria, etc.).

Here's a breakdown of the other characteristics:

A.Unicellular: Prokaryotic cells are typically unicellular ...
