B. `N_2 and NH_3`
C. `CO_2 and NH_3 `
D. `H_2 and N_2 `

Explanation

To determine which gases can be completely separated from a mixture using water as a solvent, we need to identify which gases dissolve in water. Here’s a step-by-step solution:

### Step 1: Understand the Problem
We need to find out which gases from the given options can dissolve in water. Only the gases that dissolve in water can be separated completely using water as a solvent.

### Step 2: Analyze Each Gas
