D. `C_(6)H_(5)CONH_(2)`.

Explanation

To solve the problem of what product is formed when benzaldehyde reacts with methyl amine, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are benzaldehyde and methyl amine.
- Benzaldehyde (C6H5CHO) consists of a benzene ring (C6H5) attached to a carbonyl group (CHO).
- Methyl amine (CH3NH2) consists of a methyl group (CH3) attached to an amine group (NH2).

### Step 2: Understand the Reaction Mechanism
When benzaldehyde reacts with methyl amine, a condensation reaction occurs. This involves the nucleophilic attack of the amine on the carbonyl carbon of the aldehyde.

### Step 3: Formation of the Intermediate
The nitrogen atom in methyl amine attacks the carbon atom of the carbonyl group in benzaldehyde, leading to the formation of a tetrahedral intermediate. This intermediate has both the amine and the aldehyde functional groups.

### Step 4: Elimination of Water
In the next step, the tetrahedral intermediate undergoes dehydration (removal of water). This involves the elimination of a water molecule (H2O). The oxygen from the carbonyl group of benzaldehyde and one hydrogen from the amine contribute to the formation of water.

### Step 5: Formation of the Product
After the elimination of water, the remaining parts of the reactants combine to form an imine. The product formed is called benzylidene methyl amine, which has the structure:
- C6H5-CH=NH-CH3

### Step 6: Write the Final Product Structure
The final product can be represented as:
- C6H5-CH=NH-CH3

### Conclusion
Thus, the product formed when benzaldehyde reacts with methyl amine is benzylidene methyl amine.
