C Correct answer
Explanation

Initial sugar = 20% of 5L = 1L. Total volume after adding 1L water = 6L. New concentration = (1 / 6) * 100 = 16.66%.

AI explanation

The initial amount of sugar is 20 percent of 5 liters, which equals 1 liter. After adding 1 liter of water, the total volume becomes 6 liters. Using the percentage formula, the new strength is (1 divided by 6) multiplied by 100, resulting in 16.66 percent.
