Among the following, the solution which shows the lowest osmotic pressure is:

Options

A. 0.1 M NaCl
B. `0.05 M CaCl_(2)`
C. `0.04 M K_(3)[Fe(CN)_(6)]`
D. `0.03 M FeCl_(3)`

Explanation

To determine which solution has the lowest osmotic pressure, we can use the formula for osmotic pressure (π):

\[ \pi = I \times C \times R \times T \]

Where:
- \( \pi \) = osmotic pressure
