its definitely not Grana. Grana are the stacks of thylakoid membranes. Stroma is the fluid within inside the choloroplast.
It definitely have two membranes.
And Chloroplast were formed by endosymbiosis of bacteria which does contain circular DNA.

So i would go for E, Endoplasmic Reticulum.

Grana are there
Stroma is there
Membranes are definitely there!

As for DNA, there are three types: chromosome, mitochondria, and chloroplast.

Your answer should be E.R.

yes. i agree with everyone else. ER is the answer.
