Which of the following has highest conductivity in water ?

Options

A. `Fe[Fe(CN)_(6)]_(2)`
B. `K_(3)[Fe(CN)_(6)]`
C. `Ag(NH_(3))_(2)CI`
D. `[Cr(NH_(3))_(6)]CI_(6)`

Explanation

To determine which coordination compound has the highest conductivity in water, we need to analyze the dissociation of each compound into its constituent ions. Conductivity in water is directly related to the number of ions produced when a compound dissolves. The more ions produced, the higher the conductivity.

### Step-by-Step Solution:

1. **Understand the Concept of Conductivity**:
- Conductivity of an electrolyte in water is directly proportional to the number of ions produced when it dissolves.

**Hint**: Remember that more ions mean better conductivity.
