Correct Answer
Option A is the correct answer.
Detailed Explanation
Inside the chloroplast, the inner membrane forms a complex system of interconnected sacs called thylakoids. Thylakoids are often stacked into grana. The fluid-filled space surrounding the thylakoids is called the stroma, where the dark reactions (Calvin cycle) take place.
Hint
The sacs are first, the fluid is second. Think of the sacs as coin stacks in a watery gel.
