A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na⁺K⁺ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because
(A) ATP is produced through this transporter
(B) both ions are moved via active transport
(C) both ions are moved via passive transport
(D) ATP hydrolysis does not occur during transport
