Answer

To analyze the statements provided in the question, we will evaluate each statement one by one and determine their validity based on the principles of redox reactions.

### Step-by-Step Solution:

**Step 1: Evaluate Statement 1**
The reaction given is:
\[ \text{Zn(s)} + \text{Cu}^{2+}(aq) \rightarrow \text{Zn}^{2+}(aq) + \text{Cu(s)} \]

- In this reaction, zinc (Zn) is oxidized to zinc ions (\( \text{Zn}^{2+} \)) by losing two electrons:
\[ \text{Zn} \rightarrow \text{Zn}^{2+} + 2e^- \]
- Copper ions (\( \text{Cu}^{2+} \)) are reduced to copper (Cu) by gaining those two electrons:
\[ \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} \]

Thus, copper ions act as the oxidizing agent (they gain electrons), and zinc acts as the reducing agent (it loses electrons).
**Conclusion:** Statement 1 is **True**.

**Step 2: Evaluate Statement 2**
The statement claims that every redox reaction cannot be split into two reactions, one being oxidation and the other being reduction.

- By definition, a redox reaction involves both oxidation (loss of electrons) and reduction (gain of electrons).
- Therefore, it is always possible to split a redox reaction into its oxidation and reduction half-reactions.

**Conclusion:** Statement 2 is **False**.

**Step 3: Evaluate Statement 3**
The statement discusses oxidation numbers, stating that they are artificial and useful as a bookkeeping device of electrons in reactions.

- Oxidation numbers are indeed assigned based on certain rules and are not necessarily reflective of actual charge distribution in molecules. They serve as a tool to track electron transfer during reactions.
- Therefore, it is accurate to describe oxidation numbers as artificial constructs that help in understanding redox processes.

**Conclusion:** Statement 3 is **True**.

### Final Evaluation of Statements:
- Statement 1: True
- Statement 2: False
- Statement 3: True

Thus, the overall conclusion is **TFT** (True, False, True).

### Answer:
The correct answer is **D** (TFT).
