A gaseous mixture of A, B and C is pased through water. The gaseous mixture B and C remains. If this gaseous mixture of B and C is subjected to sudden expansion followed by application of high pressure, B liquefies leaving behind C. Identify the set of gases.

Options

A. `SO_3, NO_2, O_2`
B. `Cl_2, SO_2, H_2`
C. `CO_2, CO, N_2`
D. `NH_3, N_2, H_2`

Explanation

To solve the problem, we need to identify the gases A, B, and C based on the information provided. Let's break it down step by step.

### Step 1: Analyze the given information
We have a gaseous mixture of A, B, and C that is passed through water. After passing through water, gases B and C remain, indicating that A must be a gas that is soluble in water.

**Hint:** Identify which gas is likely to dissolve in water.

### Step 2: Identify gas A
