In What Way Does the Transportation of Phloem Sap Require

In what way does the transportation of phloem sap require metabolic energy?

A) Active transport is necessary to transport sucrose against the concentration gradient at the sink.
B) The flow of water from the xylem into the phloem tube requires active transport.
C) The positive pressure potential (pushing from the source) requires ATP.
D) The flow of sucrose between sieve tubes requires active transport.
E) Drawing water from the xylem requires facilitated transport (i.e., ATP) .
