Solution

The correct option is B
Grana refers to the stacks of thylakoids

Chloroplast is bounded by a double layered membrane. There are two distinct structures present inside the chloroplasts. One is grana while the other is stroma. Grana is made up of stacks of disc-shaped structures known as thylakoids. These contain chlorophyll and are the functional units of chloroplasts.
