The correct answer is A) Nucleoid and Chromatin.
Prokaryotes (like bacteria) lack a membrane-bound nucleus. Their genetic material (usually a single circular chromosome) is located in a region of the cytoplasm called the nucleoid. Eukaryotes (like plants and animals) have a membrane-bound nucleus containing their genetic material, which is organized into multiple linear chromosomes composed of DNA wrapped around proteins (histones) forming a structure called chromatin.
The nucleolus is a dense structure found within the eukaryotic nucleus, involved in ribosome synthesis, not the primary form of the entire genetic material itself. Chromatin is the complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
