Benedict's test is used for the estimation of reducing sugars. This test is generally used to test for the presence of glucose (a reducing sugar) in urine. The colour of precipitate gives an estimation of percentage of sugar present in urine as follows:

• Blue - nil
• Green - 0.5 - 1 %
• Yellow - 1 - 2%
• Brick red - 2% or more

So, the correct answer is '2.0'.
