The genetic material of prokaryotes, organisms that do not have a nucleus or other membrane-bound organelles, is typically organized into a central area of the cell called the nucleoid. Therefore, option 1 and option 3 correctly associate prokaryotes with nucleoids.

Eukaryotes, organisms with a nucleus and other membrane-bound organelles, package their genetic material into a substance called chromatin that resides within the nucleus. This makes option 1 and 4 viable in terms of eukaryotic genetic material.

However, the nucleolus, mentioned in option 3 and 4, is not the genetic material but a smaller structure within the nucleus that`s involved in ribosome production.

So, only option 1 "Nucleoid and Chromatin" correctly identifies the respective structures for storing genetic material in prokaryotes and eukaryotes respectively, making it the correct answer.
