Answer:
A)The nucleus directs cellular activity and stores hereditary information.
Step-by-step explanation:
The nucleus contains *chromatin and one or more denser, granular structures called nucleoli*. The *chromatin is a complex of DNA and histone and non histone protein, and it carries genetic/hereditary information of the cell*.* Nucleoli (sing. Nucleolus) are specialized parts of certain chromosomes that carry multiple copies of the DNA information to synthesize ribosomal RNA*. After transcription from the nuclear DNA, the RNA combines with several different proteins to form a ribosome, detaches from the nucleolus and passes through nuclear pores to the cytoplasm. The Nucleus also directs cellular activity.
In otherwords, Nucleus stores hereditary information and also directs cellular activity.
