Okay, I may sound weird, but I LOVE this question. Finally someone asked it, because explaining it is fun, lol. Anyway, think of it like this. When you take a bath, you wait for it to fill up. When it gets to the top, you think it is full. Although when you sit inside of it, the water may overflow. This is because you are taking up volume. (This doesn't just happen with a bath, it happens when any object is submerged in the water). Just like in the picture, these sugar molecules are taking up space. The barrier is permeable with water but not sugar, so that means that the amount of sugar molecules will not change at all. So eliminate both of the answers that have to deal with sugar moving. Think about it, water moves high to low through osmosis. The particles keep moving and then eventually reach equilibrium. Once they reach equilibrium, the same amount of water will be on both side A and B. But the thing is that it won't look like the same amount. Think back to the bath analogy. Imagine two baths in the same room, and fill them up both with the same amount of water. Then put "low concentration" or a little bit of solids inside of Bath A. The water will rise a little bit. Then, put "high concentration" or a lot of solids inside of Bath B. The water rises more in the second bath, because the solids are taking up a lot of volume inside the liquid, if that makes sense? So basically to answer your question, the answer should be A. Side A will have less water, and Side B will have more water. That was a lot of random information, so you might have a lot of questions. If you are wondering anything, then just ask it in the comments and I will try my best to answer it! Hope I helped! :)
