Solution

The correct option is C
Rough Endoplasmic Reticulum

Lysosomes are known to contain more than 60 different enzymes. Enzymes of the lysosomes are synthesised in the rough endoplasmic reticulum. The enzymes are imported from the Golgi apparatus in small vesicles, which fuse with larger acidic vesicles. Enzymes destined for a lysosome are specifically tagged with the molecule mannose 6-phosphate so that they are properly sorted into acidified vesicles
