Answer:
b. some sodium iodide will precipitate out of solution

Thus,the undissolved sodium iodide will precipitate out of the solution.

Just as the prism below refracts light at its faces, seismic waves bend, reflect and change speed at the boundaries between different materials below the Earth's surface.
