First, I’ll restate the question and list the answer choices to set the context.
Question: What is the highest Normal Form of the following table? Each Girl can grow more than one Flower and lives at one Address.
Answer choices: 3NF, None of the answers., 1NF, 2NF

Now, evaluate each option in turn.
Option 1: 3NF
- To be in 3NF, a relation must be in 2NF and have no transitive dependencies. This table already has a non-atomic column for Flower (a single row contains multiple flowers: Daisy, Daffodil). This clearly violates 1NF, which means it cannot be in 2NF or 3NF either. Since 3NF requires at least 2NF (and in practice, to be in 3NF you must be in 2NF), this option is incorrect because the table fails basic 1NF requirements.
Option 2: None of the answers.
- This option would be correct if none of the listed normal forms (3NF, 1NF, 2NF) apply. Given the analysis, the table does not satisfy 1NF due to multi-valued flower data, so it cannot be in 2NF or 3NF either. Therefore, among the provided choices, this option is a plausible candidate because all the listed NF levels fail.
Option 3: 1NF
- 1NF requires that all attribute domains be atomic (no repeating groups). Here, the Flower column contains values like "Daisy, Daffodil" in a single field, which is a repeating group within a row. This violates 1NF directly. Therefore, this option is incorrect.
Option 4: 2NF
- 2NF requires the relation to be in 1NF and have no partial dependency of any non-key attribute on a candidate key. Since the table is not in 1NF due to the multi-valued Flower field, it cannot be in 2NF either. Thus this option is incorrect.

Summarizing the reasoning: The table violates 1NF because the Flower column holds multiple values in a single cell. Because 1NF is violated, the table cannot be in 2NF or 3NF, and it certainly isn’t in any higher NF. Among the given options, the only one that correctly reflects the situation is "None of the answers" since none of 1NF, 2NF, or 3NF apply. The core misconception in some options is assuming atomic values and standard dependencies when the data structure explicitly allows multi-valued attributes in a single row, which breaks the baseline requirement for 1NF.
