C Correct answer
Explanation

Initial sugar = 5% of 6 liters = 0.3 liters. After evaporating 1 liter, total volume = 5 liters. New percentage = (0.3 / 5) * 100 = 6%.

AI explanation

In the original 6 litres of solution, the amount of pure sugar is 5 percent of 6, which equals 0.3 litres. After 1 litre of water evaporates, the total volume of the remaining solution becomes 5 litres. The new percentage of sugar is calculated as (0.3 / 5) * 100, which equals 6 percent.
