Solution

The correct option is A is higher than that at a dilute solution.
According to the definition of the osmotic pressure, we know that:

$π = C R T .$

For the concentrated solution, C has a higher value than the dilute solution.

Therefore, as the concentration of the solution increases the osmotic pressure will also increase.

Thus option A is correct.
