The given diagram illustrates the presence of

Options

  1. AAmylose in aqueous solution
  2. BAmylopectin in aqueous solution
  3. CIodine in aqueous solution
  4. DBoth amylose and iodine in the solution

Correct answer

D. Both amylose and iodine in the solution

Step-by-step solution

Starch can be used as an indicator for the detection of traces of iodine in aqueous solution. Amylose is responsible for the formation of deep blue colour in the test for the presence of starch. The action of amylase enzyme breaks the amylose into glucose molecules and the blue colour will not be formed.
