Read the following statements. The correct symbols filling the blanks A and B are

Osmotic Pressure of a concentrated solution                A               osmotic pressure of a dilute solution. Diffusion pressure deficit of a concentrated solution               B               diffusion pressure deficit of a dilute solution.

Mitochondria and chloroplast are:

(i) Semi - autonomous organelles

(ii) Formed by the division of pre-existing organelles and they contain DNA but lack protein synthesizing machinery

Which one of the following option is correct?

Assertion ($\mathrm{A}$): The flow of solvent molecules from a pure solvent to the solution through semipermeable membrane is osmosis.

Reason $\left(\mathrm{R}\right):$ Pure solvent molecules flow out of the solution through semipermeable membrane if a pressure larger than the osmotic pressure is applied to the solution side.

The correct answer is:
