You are asked to prepare oxygen from air after eliminating the impurities in the order that is at first dust particles then water vapour and `CO_(2)` at the end. Based on the given instruction arrange the processes given below in a sequence.
(a) Passing the sample of air through concentrated NaOH
(b) Repeated compression followed by sudden expansion
(c) Fractional distillation of liquefied air
(d) Passing the air through electrostatic precipitator
(e) Passing the air through anhydrous `CaCl_(2)`

Options

A. a d e b c
B. a c e b d
C. d e a b c
D. b a e d c

Explanation

To prepare oxygen from air while eliminating impurities in the specified order (dust particles, water vapor, and CO2), we can follow these steps:

### Step-by-Step Solution:

1. **Remove Dust Particles**:
- The first step is to remove dust particles from the air. This can be accomplished by passing the air through an **electrostatic precipitator**. This device uses electrical energy to attract and collect dust particles from the air.

2. **Remove Water Vapor**:
