Salt balance in humans is primarily controlled by the kidneys, which regulate the excretion of salt through urine. The body also has mechanisms to regulate salt intake through thirst and salt appetite, but these are secondary to the renal regulation of salt balance. Therefore, option B correctly describes the primary control of salt balance in humans.
