B. 2 4 1 3 5
C. 4 2 3 1 5
D. 4 5 2 3 1

Explanation

To arrange the steps in the process of the carbon cycle starting from the abundant state of existence of carbon in the combined state, we can follow these steps:

1. **Carbon Dioxide (CO₂) in the Atmosphere**: The cycle begins with carbon existing in the atmosphere as carbon dioxide. This is the most abundant state of carbon in the combined form.

2. **Plants**: Plants absorb carbon dioxide from the atmosphere during the process of photosynthesis. They convert CO₂ into glucose (C₆H₁₂O₆) using sunlight.

3. **Organic Matter**: When plants die or when they are consumed by animals, they become part of the organic matter. This organic matter includes all the biological material that was once living.
