Answer:
c) There will be a net movement of salt from side B to side A
Explanation:
According to the given information, the solution at side A is hypotonic to the solution at side B. The separating membrane is permeable to salt and would allow the movement of salt from the hypertonic side B to the hypotonic side A. Transport of substances down their concentration gradient is a passive movement and occurs from the region of higher concentration of the substance to that of its lower concentration.
