Answer

To determine which of the given options is not a statement, we first need to understand what a statement is. A statement is a declarative sentence that can be classified as either true or false.

Let's analyze each option step by step:

1. **Option 1: "The sky is blue."**
- This is a declarative sentence.
- It can be evaluated as true or false depending on the time of day and weather conditions.
- Therefore, this is a statement.

2. **Option 2: "The sky is dark in the night."**
- This is also a declarative sentence.
- It can be evaluated as true (since the sky is generally dark at night).
- Therefore, this is a statement.

3. **Option 3: "The sky is not blue in the night."**
- This is another declarative sentence.
- It can also be evaluated as true (as the sky is typically not blue at night).
- Therefore, this is a statement.

4. **Option 4: "Sky blue."**
- This is not a complete sentence.
- It does not express a complete thought and cannot be evaluated as true or false.
- Therefore, this is not a statement.

Based on this analysis, the option that is not a statement is **Option 4: "Sky blue."**
