Maple syrup is made from the sap of the sugar maple tree. Why does is take so much energy to make maple syrup?

A) The sap of the maple tree must first be distilled to remove the impurities. This is a very slow and tedious process requiring a great deal of energy.
B) The sap of the maple tree must undergo fractional separation in order to extract the delicate maple syrup. The separation process is very energy intensive.
C) Producing maple syrup requires boiling away most of the water from the sap. The resulting concentrated solution is maple syrup. A lot of energy is required to boil away the water.
D) The maple syrup would extract itself from the sap over a relatively short period of time. However, because manufacturers don't wish to wait for the natural process, they pour huge amounts of energy into a process to speed up the reaction.
