Answer

To determine which of the given options is not a statement, we need to analyze each option to see if it can be classified as either true or false.

1. **Roses are red**: This is a declarative sentence that can be evaluated as true (in a poetic sense) or false (in a literal sense). Thus, it can be classified as a statement.

2. **New Delhi is in India**: This is a factual statement that can be confirmed as true. Therefore, it is also a statement.

3. **Every square is a rectangle**: This is a mathematical statement that is true. Hence, it is classified as a statement.

4. **Alas, I have failed**: This expression conveys an emotion or sentiment rather than a factual assertion that can be evaluated as true or false. Therefore, it does not qualify as a statement.

Based on this analysis, the option that is not a statement is **"Alas, I have failed."**
