Solution

The correct option is C bacteria and cyanobacteria
Nuclear material in prokaryotes is ‘naked’ meaning that it is not enveloped by any nuclear membrane. Prokaryotes include bacteria, cyanobacteria (blue-green algae) and mycoplasma.

Algae are eukaryotic. In eukaryotic organisms, the genetic material is well enclosed by a distinct nuclear membrane and is said to be a true nucleus.
