C. `273^(@)C`, `1 atm`
D. `273^(@)C`, `2 atm`

Explanation

To solve the question about the density of neon gas and determine at which conditions it will be highest, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ideal Gas Law**:
The ideal gas law is given by the equation \( PV = nRT \), where:
- \( P \) = pressure
- \( V \) = volume
