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 shows the lowest osmotic pressure among the given options, we will use the formula for osmotic pressure, which is given by:

\[ \pi = i \cdot C \cdot R \cdot T \]

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