{'reverse osmosis': [0, 0, 1, 0], 'osmosis': [2, 0, 0, 2], 'dilute solution': [0, 0, 1, 1], 'external pressure': [0, 0, 1, 0], 'concentrated solution': [0, 0, 1, 1], 'solvent': [0, 0, 3, 1], 'process': [16, 0, 12, 37]}

In option 1, the statement is incorrect. During the process of osmosis, the solvent actually travels from a region of lower concentration (the dilute solution) to a region of higher concentration (the concentrated solution), not the other way around.

Option 2 is correct. In reverse osmosis, external pressure is indeed applied to the concentrated solution side. This pressure acts against the osmotic pressure, forcing the solvent to move from concentrated solution to dilute solution across a semipermeable membrane.

Option 3 suggests both statements are correct, which is not the case because the first statement is incorrect.

Option 4 infers that neither of the statements is correct, but we know the second statement is correct. Hence, the correct answer is option 2.
