Answer

  1. Both B and C

Explanation:

Prokaryotes do not possess membrane-bound organelles and well-defined nucleus.

Nucleoid is a region in a prokaryotic cell, where most of the genetic material resides.

It is not a well-defined membrane-bound region. 

Eukaryotes possess a well-defined nucleus and membrane-bound organelles as mitochondria, Golgi complex, etc. Nucleus is bound with double membrane in eukaryotic cells in which most of the genetic material is present.
