When asked to set up an experiment to show that 'light is necessary for photosynthesis', a student ran to the school garden and set up the experiment by using a plant growing in the school garden.The experiment failed.His classmates made the following suggestions to get success in the experiment:
Student A : Safranin should be used instead of iodine
Student B : The leaf should not be boiled in alcohol to remove chlorophyll before testing for starch
Student C : Transparent paper should be used instead of black paper strip
Student D : The leaf should be destarched before starting the experiment. 
 The correct suggestion is given by:

 An  absolute requirement  in the process of photosynthesis is
