**Question 12**

**Which chemical system is consistent with the graph shown below?**

*Graph Description:* 

The graph illustrates the relationship between concentration (M) and time (s) for three chemical species labeled A, B, and C. 

- The concentration of chemical A increases steadily over time, starting from 0 M at 0 s to reaching approximately 0.03 M at 800 s.
- The concentration of chemical B decreases sharply over time, starting from 0.02 M at 0 s and dropping to nearly 0.00 M by 800 s.
- The concentration of chemical C increases gradually over time, starting from 0 M at 0 s and rising to around 0.01 M by 800 s.

The different concentrations of these chemicals are plotted on the y-axis, while the x-axis represents time in seconds (s). The points on the graph indicate the measured concentration values at various time intervals, connected by lines to show the trend over time.

**Options:**
1. 4A(g) → B(g) + 2C(g)
2. 4A(g) + B(g) → 2C(g)
3. 2C(g) → 4A(g) + B(g)
4. 2C(g) + B(g) → 4A(g)

**Answer:**
*(Please select the correct chemical system based on the graph)*
