(b) Carbon dioxide
( c) Oxygen
(d) Argon

Options

A. bdca
B. acdb
C. dcba
D. bacd

Explanation

To arrange the components of air in the increasing order of their percentage by volume, we first need to know the approximate percentages of each component in the air:

1. **Nitrogen (N2)**: Approximately 78.084%
2. **Oxygen (O2)**: Approximately 20.947%
3. **Argon (Ar)**: Approximately 0.934%
4. **Carbon Dioxide (CO2)**: Approximately 0.033%

Now, we will arrange these components in increasing order based on their percentages:

1. **Carbon Dioxide (CO2)**: 0.033%
2. **Argon (Ar)**: 0.934%
3. **Oxygen (O2)**: 20.947%
4. **Nitrogen (N2)**: 78.084%

Thus, the increasing order of the components of air by their percentage by volume is:

**Carbon Dioxide < Argon < Oxygen < Nitrogen**
