✓

Answer

Correct option: A.

Enzymes packed in lysosomes are made through $\text{RER}\ ($Rough Endoplasmic Reticulum$)$.

The undefined nuclear region is the cytoplasm of prokaryotic cells is called nucleoid.
The prokaryotic cells consist of a single chromosome, which is direct content of the cytoplasm i.e., there is no nuclear membrane in a eukaryotic cell, the nuclear envelope separates the nucleus from the cytoplasm.
The nuclear envelope contains many pores $($the nuclear pores$)$ and encloses the liquid ground substance, the nucleoplasm. Within nucleoplasm two types of nuclear structures are embedded$-$the nucleolus and chromatin material.
The nucleolus may be one or more in number and is not bounded by any membrane. It is rich in protein and $\text{RNA}\ ($Ribonucleic Acid$)$ molecules and acts as the site for ribosome formation, hence are also known as factory of ribosomes.
