Solution

The correct option is B

It contains the hereditary material


The nucleus is an organelle found in eukaryotic cells. Inside its nuclear membrane, it contains the majority of the cell's genetic material, DNA. DNA in association with a variety of proteins forms thread-like structures called chromatin fibres. These fibres condense during cell division to form chromosomes.
