B. `-202.6 J`
C. `-506 J`
D. `-101.3 J`

Explanation

To solve the problem of calculating the work done by the system during a single-stage expansion process, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Process**:
- The problem describes a single-stage expansion process where the gas expands against a constant pressure of 1 atm.

2. **Understand the Work Done Formula**:
