The correct answer is: B.It is linear and contained within the nucleus.

Explanation:

In eukaryotic cells, the genetic material is linear DNA, and it is located in the nucleus, which is a membrane-bound compartment within the cell. This linear DNA forms the chromosomes, and it contains the instructions for the cell's functions and reproduction.

Let's break down the other options:

A.It is circular and located in the cytoplasm: This is false. Circular DNA is typically found in prokaryotic cells (e.g., in bacteria), and in mitochondria or chloroplasts of eukaryotic cells (which are thought to have originated from endosymbiotic prokaryotes), but the main genetic material in eukar...
