JEE Main Chemistry question

During osmosis, flow of water through a semipermeable membrane is

(A)From both sides of semipermeable membrane with unequal flow ratesCorrect
(B)From solution having lower concentration only
(C)From solution having higher concentration only
(D)From both sides of semipermeable membrane with equal flow rates

Answer: (A)

Solution

Water molecules actually move across the membrane in both directions simultaneously, but at different rates; the net flow (the physically observable osmotic flow) is from the
