Solution

The correct options are
A Nucleolus
B
The nucleus controls the working of the cell

C
Mitochondria contain DNA

The nucleolus is present inside the nucleus and is the site where ribosomes are synthesized. The nucleus is also known as the brain of the cell as it controls cellular functions like protein synthesis. Mitochondria and chloroplasts are the only two organelles other than nucleus which contain their own genetic material. Ribosomes are synthesized in the nucleus. They are scattered within the cytoplasm or attached to Endoplasmic Reticulum.
