D. `CH_(3) CH_(2) CH_(2) CH_(3)`

Answer

To solve the question of what is obtained when diethyl ether (C₂H₅OC₂H₅) is heated with concentrated sulfuric acid (H₂SO₄), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactant is diethyl ether (C₂H₅OC₂H₅), which is an ether. The other reactant is concentrated sulfuric acid (H₂SO₄).

2. **Understand the Reaction Conditions**: When ethers are treated with concentrated sulfuric acid, they undergo a reaction that typically leads to the formation of alcohols and alkyl hydrogen sulfates.

3. **Reaction Mechanism**:
- When diethyl ether is heated with concentrated H₂SO₄, the ether undergoes protonation. The ether oxygen atom gets protonated, making it a better leaving group.
- This leads to the cleavage of the C-O bond in the ether, resulting in the formation of ethyl alcohol (C₂H₅OH) and ethyl hydrogen sulfate (C₂H₅OSO₃H).

4. **Write the Products**: The products formed from this reaction are:
- Ethyl alcohol (C₂H₅OH)
- Ethyl hydrogen sulfate (C₂H₅OSO₃H)

5. **Conclusion**: Therefore, when C₂H₅OC₂H₅ is heated with concentrated H₂SO₄, the products obtained are ethyl alcohol and ethyl hydrogen sulfate.

### Final Answer:
The products obtained are ethyl alcohol (C₂H₅OH) and ethyl hydrogen sulfate (C₂H₅OSO₃H).
