Solution
The correct option is B Active transport
The
movement of sodium ions utilizes ATP. This utilization of an ATP molecule provides
the cell with an energy boost which enables the transport the sodium ions
across the cell membrane. This is an example of active transport of molecules across
the cell membrane.
