Option "D" is incorrect.
Option "A" is correct.
- ER always forms a network system.
- It is large network of membrane bound sheets and tubes.

- It also Provide surface for some Biochemical activities.
- It also serve as a channel for transportation of material between cytoplasm and nucleus.
option "B" is also correct.
- Golgi appratus helps in the formation of Lysosomes.
- During the disturbance of cellular metabolism or when the cell get damaged it may burst and digest their own cell.
- Lysosomes are kind of waste disposal system of the cell, it helps in cleaning the cell by digest foreign material as well as worn out cell Organelles.
- All the bacterias, microorganisms and Foreign materials end up in Lysosomes.
Option "c" is also correct.
- Mitochondria is known as powerhouse of the cell as it helps in respiration.
- When the mitochondria needed energy for making new chemical compound and for mechanical work the ATP molecules breaks down to provide energy
- They are strange Organelles because they have their own DNA and Ribosomes.
