Which of the following is incorrect sequence?

Options

A. Palaeozoic-Mesozoic-Coenozoic
B. Triassic-Jurassic-Cretaceous
C. Silurian-Devonian-Carboniferous
D. Devonian-Permian-Carboniferous

Answer

To determine the incorrect sequence in geological history, we need to analyze the sequences provided in the question.

### Step-by-Step Solution:

1. **Understanding Geological Eras**:
- The geological history of Earth is divided into different eons, eras, periods, and epochs. The Phanerozoic eon is divided into three main eras: Paleozoic, Mesozoic, and Cenozoic.

2. **Identifying the First Sequence**:
- The first sequence provided is Paleozoic, Mesozoic, Cenozoic.
- This is the correct order of the three main eras in the Phanerozoic eon.

3. **Identifying the Second Sequence**:
- The second sequence is Triassic, Jurassic, Cretaceous, which are periods within the Mesozoic era.
- This is also the correct order, as the Triassic period comes first, followed by the Jurassic, and then the Cretaceous.

4. **Identifying the Third Sequence**:
- The third sequence is Silurian, Devonian, Carboniferous.
- This sequence is correct as well, since the Silurian period is followed by the Devonian, and then the Carboniferous occurs later in the Paleozoic era.

5. **Identifying the Fourth Sequence**:
- The fourth sequence is Devonian, Permian, Carboniferous.
- This sequence is incorrect because the Carboniferous period occurs after the Devonian and before the Permian in the Paleozoic era.

6. **Conclusion**:
- The incorrect sequence among the options given is the fourth one: Devonian, Permian, Carboniferous.

### Final Answer:
The incorrect sequence is **Devonian, Permian, Carboniferous** (Option 4).
