Solution

The correct option is C
1=Outer membrane, 2= Inner membrane, 3= Grana, 4= Thylakoids, 5= Stroma

Two membranes contain and protect the inner parts of the chloroplast. They are appropriately named the outer and inner membranes. The inner membrane surrounds the stroma and the grana (stacks of thylakoids). One thylakoid stack is called a granum.
1=Outer membrane., 2= Inner membrane., 3= Grana. ,4= Thylakoids ., 5= Stroma
