During active transport a material perhaps move from a region of low concentration to a high concentration area.

Answer: A

Explanation:

The reason for considering alternative statement as false are:

• Throughout passive transport energy isn't used to move materials against a concentration gradient whereas in active transport, energy is employed to move materials against a concentration difference.

• Throughout passive transport osmosis enable solvents to pass from the one end to the opposite end of the membrane to equalize concentration on each side. It doesn't permit salt to move.
