B. `LiAlH_(4)`
C. `Conc.HNO_(3)`
D. `Aqueous KOH`

Answer

To convert Benzamide to Benzylamine, we need to follow a reduction reaction. Here’s a step-by-step solution:

### Step 1: Identify the Reactants
- We start with Benzamide (C6H5CONH2) as our starting material.

### Step 2: Choose the Suitable Reagent
- The most suitable reagent for the conversion of Benzamide to Benzylamine is Lithium Aluminium Hydride (LiAlH4). This reagent is known for its strong reducing properties.

### Step 3: Reaction Mechanism
- When Benzamide is treated with Lithium Aluminium Hydride, the carbonyl group (C=O) of the amide is reduced to a primary amine.
- The reaction can be represented as follows:
\[ \text{C}_6\text{H}_5\text{CONH}_2 + \text{LiAlH}_4 \rightarrow \text{C}_6\text{H}_5\text{CH}_2\text{NH}_2 + \text{by-products} \]
- In this reaction, the carbonyl oxygen is removed, and the amide is converted to Benzylamine (C6H5CH2NH2).

### Step 4: Final Product
- The final product of this reaction is Benzylamine, which has the structure C6H5CH2NH2.

### Conclusion
- Therefore, the most suitable reagent for the conversion of Benzamide to Benzylamine is Lithium Aluminium Hydride (LiAlH4).
