Is this an example of osmosis?

Question

In the image, the dashed line represents a membrane separating 2 solutions that is selectively permeable to solutes. The solution on the left is Solution A (50 mg/ml). The solution on the right is Solution B (75 mg/ml). 

What type of movement, if any, is occurring across the membrane?

a. active transport

b. diffusion

c. osmosis

d. facilitated diffusion

Answer 1

I can't see the diagram you are referring to but if the barrier allows water to pass thru then it will travel to the higher concentration of solution B, which is the process of osmosis, a type of diffusion.
