(D) The mass flow hypothesis,also known as the pressure-flow hypothesis,was first proposed by Ernst $M$ünch in $1930$. This hypothesis explains the mechanism of translocation of sugars (sucrose) from the source (leaves) to the sink (roots,fruits,etc.) through the phloem. According to this theory,a pressure gradient is created due to the osmotic movement of water into the phloem,which drives the bulk flow of sap.
