Answer:

Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.
