To balance the skeleton equation \( \text{NO} \rightarrow \text{N}_2 + \text{O}_2 \), we need to ensure that the number of each type of atom on the reactant side equals the number on the product side.

1. **Counting atoms in the unbalanced equation:**
- **Reactants:**
- 1 Nitrogen (N) from NO
- 1 Oxygen (O) from NO
- **Products:**
- 2 Nitrogens (N) from N₂
- 2 Oxygens (O) from O₂

2. **Balancing Nitrogen:**
To balance Nitrogen, we put a coefficient of 2 in front of NO:
\[
2 \text{NO} \rightarrow \text{N}_2 + \text{O}_2
\]

3. **Counting atoms again:**
- **Reactants:**
- 2 Nitrogens (N)
- 2 Oxygens (O)
- **Products:**
- 2 Nitrogens (N)
- 2 Oxygens (O)

4. **Final balanced equation:**
\[
2 \text{NO} \rightarrow 1 \text{N}_2 + 1 \text{O}_2
\]

Thus, the coefficients that balance the equation are **2, 1, 1**.

So the correct response is:
**2, 1, 1**.
