Explanation

To convert atmospheric water vapor into underground water, we can arrange the steps in the following sequence:

1. **Precipitation (d)**: This is the first step where atmospheric water vapor condenses and falls to the ground in the form of rain, snow, or other forms of moisture.

2. **Infiltration in zone of aeration (c)**: After precipitation, the water begins to infiltrate the ground. The first layer it enters is the zone of aeration, which is the area above the water table where soil pores are filled with both air and water.

3. **Infiltration in recharge area (a)**: Next, the water continues to infiltrate into the recharge area, which is a specific area where water enters an aquifer.

4. **Water table (b)**: As the water continues to move down, it reaches the water table, which is the upper surface of the saturated zone in the ground.

5. **Aquifer (e)**: Finally, the water accumulates in an aquifer, which is a geological formation that can store and transmit groundwater.

So, the correct order is:
**d → c → a → b → e**
