Which of following statements does not apply to reverse osmosis?

Options

A. It is used for water purification
B. In this technique, pressure greater than osmotic presure is applied to the system
C. It is a passive process
D. It is an active process

Explanation

Reverse osmosis is not an active process (in organisms) is considered active when its completion requres energy in from of ATP. And as reverse osmosis does not consume ATP, it is a passive, through external pressure is applied in order to carry out osomosis in a reverse direction (lower to higher).
Rest of the options are true for reverse osmosis.
