A beaker is divided into two compartments by a semipermeable membrane.Compartment A contains a 20% NaCl solution while compartment B contains a 50% NaCl solution.The membrane is permeable to both water and Na⁺ and Cl^-.Initially,

A) Na⁺ and Cl^- diffuse from compartment B to compartment A.
B) water diffuses from compartment B to compartment A.
C) Na⁺ and Cl^- diffuse from compartment A to compartment B.
D) Na⁺ diffuses from compartment A to compartment B and Cl^- diffuses from compartment B to compartment A.
