B. `H_(3)BO_(3)`
C. `B_(2)O_(3)`
D. `All of these

Explanation

To solve the question "When aqueous solutions of borax are acidified with HCl, we get", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chemical Composition of Borax**:
- Borax is chemically represented as Na₂B₄O₇. It is a sodium borate compound.

2. **Understand the Reaction with Hydrochloric Acid (HCl)**:
- When borax (Na₂B₄O₇) is dissolved in water, it forms an aqueous solution. When this solution is acidified with hydrochloric acid (HCl), a chemical reaction occurs.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{Na}_2\text{B}_4\text{O}_7 + \text{HCl} \rightarrow \text{NaCl} + \text{H}_3\text{B}O_3 \]
- In this reaction, sodium chloride (NaCl) and boric acid (H₃BO₃) are formed.

4. **Identify the Products**:
- The products of the reaction are sodium chloride (NaCl) and boric acid (H₃BO₃).
- Boric acid is a weak monobasic acid and is known for its soapy touch.

5. **Conclusion**:
- Therefore, when an aqueous solution of borax is acidified with HCl, the main product formed is boric acid (H₃BO₃) along with sodium chloride (NaCl).

### Final Answer:
When aqueous solutions of borax are acidified with HCl, we get boric acid (H₃BO₃) and sodium chloride (NaCl).
