Consider three connected lakes, A, B, and C, where lake B has a volume of 2650 km2, and water flows from into lake B, and from lake B into lake C, both inflows and outflows at the same rate of 525 km/year. Suppo that at time t%3D0 (years), the pollutant concentration of lake B, caused by past industrial pollution that has no been ordered to cease, is five times that of lake A. If the outflow from lake B to lake C is perfectly mixed lake water, how long will it take to reduce the pollution concentration in lake B to twice that of lake A? (Choose a correct answers)
