The correct sequence of origin of lysosome is represented by option (a) and can be described as follows Lysosomes are believed to be formed by the joint activity of endoplasmic reticulum and Golgi complex. The precursors of hydrolytic enzymes are mostly synthesised at the rough endoplasmic reticulum.
The latter transfers them to the forming face of Golgi complex. In Golgi complex, the precursors are changed to enzymes. The enzymes are then packed in larger vesicles, which are further modified into lysosomes.
