Assertion (A): Formation of semipermeable membrane between the walls of porous pot on hanging pot filled with \( \mathrm{CuSO}_{4} \) (aq.) partially dipped in \( \mathrm{K}_{4} \mathrm{Fe}(\mathrm{CN})_{6} \) is due to osmosis.
Reason (R): The ions moves through the walls of porous pot and between the walls \( \mathrm{Cu}^{2+} \) and \( \mathrm{Fe}(\mathrm{CN})_{6}^{4} \) gives insoluble gelatinous mass of \( \mathrm{Ca}_{2}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]_{4} \).
(A) Both A and R are true and R is the correct explanation of A.br(B) Both A and R are true, but R is not the correct explanation of A.
(C) A is true, but R is false.
(D) A is false, but R is true.
(E) Both A and R are false.
