C. `Na_(2)ZnO_(2)and H_(2)`
D. Reaction arely occurs

Answer

To solve the reaction of zinc with sodium hydroxide (NaOH), we will follow these steps:

### Step 1: Identify the Reactants
The reactants in the reaction are zinc (Zn) and sodium hydroxide (NaOH).

### Step 2: Write the Balanced Equation
The reaction can be represented as:
\[ \text{Zn} + 2 \text{NaOH} \rightarrow \text{A} + \text{B} \]

### Step 3: Determine the Products
When zinc reacts with sodium hydroxide, it forms sodium zincate and hydrogen gas. The products can be identified as:
- A = Sodium Zincate (Na₂ZnO₂)
- B = Hydrogen gas (H₂)

### Step 4: Write the Complete Balanced Reaction
Now, we can write the complete balanced equation:
\[ \text{Zn} + 2 \text{NaOH} \rightarrow \text{Na}_2\text{ZnO}_2 + \text{H}_2 \]

### Step 5: Conclusion
Thus, the products of the reaction are sodium zincate (Na₂ZnO₂) and hydrogen gas (H₂).

### Final Answer
- A = Sodium Zincate (Na₂ZnO₂)
- B = Hydrogen gas (H₂)
