Solution
The correct option is B Marcello Malpighi
Italian biologist Marcello Malpighi conducted the girdling (ringing) experiment to identify the tissues responsible for the transportation of food in plants. This experiment proves that phloem is the tissue responsible for the translocation of food.
Dixon and Jolly proposed the cohesion theory or transpiration pull theory. This theory is the widely accepted theory on ascent of sap.
Ernst Munch proposed the mass flow hypothesis explaining translocation of phloem sap (sucrose and other solutes in water) along a pressure gradient.
Jan Ingenhousz showed that sunlight is essential for photosynthesis.
