The aqueous solutions of `HCOONa, C_(6)H_(5)NH_(3)CI`, and KCN are, respectively,

Options

A. acidic, acidic, basic
B. acidic, basic, neutral
C. basic, neutral, neutral
D. basic, acidic, basic

Explanation

To determine the nature of the aqueous solutions of HCOONa, C6H5NH3Cl, and KCN, we need to analyze each compound based on the acids and bases from which they are derived.

### Step 1: Analyze HCOONa
- **HCOONa (Sodium Formate)**: This is a salt formed from the weak acid formic acid (HCOOH) and the strong base sodium hydroxide (NaOH).
- **Nature of Solution**: Since it is derived from a weak acid and a strong base, the solution will be basic.

### Step 2: Analyze C6H5NH3Cl
- **C6H5NH3Cl (Benzylammonium Chloride)**: This is a salt formed from the weak base aniline (C6H5NH2) and the strong acid hydrochloric acid (HCl).
- **Nature of Solution**: Since it is derived from a weak base and a strong acid, the solution will be acidic.

### Step 3: Analyze KCN
- **KCN (Potassium Cyanide)**: This is a salt formed from the strong base potassium hydroxide (KOH) and the weak acid hydrocyanic acid (HCN).
- **Nature of Solution**: Since it is derived from a strong base and a weak acid, the solution will be basic.

### Conclusion
- The aqueous solutions of HCOONa, C6H5NH3Cl, and KCN are respectively: **Basic, Acidic, Basic**.

### Final Answer
- HCOONa: Basic
- C6H5NH3Cl: Acidic
- KCN: Basic
