Solution

The correct option is B
It contains the hereditary material

Eukaryotic cells have a well-defined nucleus. It is covered by a nuclear membrane and contains DNA - the hereditary (genetic) material of the cell.
DNA in association with a variety of proteins forms thread-like structures called chromatin fibres. These fibres condense during cell division to form chromosomes.
