The van der Waals constant for gases `A`, `B`, and `C` are as follows Which gas has the largest molecular volume?

Options

A. `A`
B. `B`
C. `C`
D. None

Explanation

To determine which gas has the largest molecular volume based on the van der Waals constants, we will follow these steps:

### Step-by-Step Solution:

1. **Understand the van der Waals Equation**: The van der Waals equation for real gases is given by:
\[ (P + \frac{a}{V_m^2})(V_m - b) = RT \]
