Solution

The correct option is D Munch
'Mass flow hypothesis' or 'Pressure flow hypothesis' to explain translocation was given by Munch, 1930.
According to this theory organic substances move in the sieve tubes from the region of high osmotic concentration to the region of low osmotic concentration in a mass flow, due to occurrence of pressure gradient. This is the most widely accepted theory to explain translocation in plants.
