The answer is B) and here's why:
since the radius of the wheel is 3 and the radius of the axle is 1 you multiply 3 by 1 which is 3. Then you multiply it with 100 so 3 x 100 is 300. But there is no 300 the closest answer is B)200. so B should be the answer

Plants competing for sunlight or growing in dark conditions will develop elongated stems and poorly developed leaves. They are often tall and thin, lacking color in their stems. In severe cases, this physiological condition is called etiolation. Therefore, the darker the environment, the taller the plants tend to be

Explanation:
The light reactions could be viewed as analogous to a hydroelectric dam. In that case, the wall of the dam that holds back the water would be analogous to the thylakoid membrane.
Thylakoid membrane is present in cyanobacteria and chloroplasts of plants. It plays a crucial role in photosynthesis and photosystem II reactions.
In general, these are the regions where light-dependent reactions take place. The thylakoid membrane is a lipid-bound membrane that maintains potential difference and also controls the flow of liquids across the membrane during light reactions.
In the provided case, we can see that the wall of the dam holds back the water, similarly, in light-dependent reactions, thylakoid membranes control the liquid flow and also regulate the potential gradient across the membrane and also allow the selective proteins to pass through.
