In the context of the diagram given below,which of the following statements is true concerning half-cell II? A) [Cu²⁺] decreases with time,and [K+] increases with time. B) [Cu²⁺] increases with time,and [K+] increases with time. C) [Cu²⁺] decreases with time,and [K+] decreases with time. D) [Cu²⁺] decreases with time,and [SO₄2-] decreases with time. E) [Cu²⁺] increases with time,and [SO₄2-] increases with time.

In half-cell II, the concentration of Cu2+ decreases as it is reduced to Cu (solid), which causes the concentration of [Cu²⁺] to decrease with time. On the other hand, K+ ions are released from the salt bridge to balance the charge and maintain electrical neutrality, causing the concentration of [K+] to increase with time.
