Consider the schema $R=(\text{S T U V})$ and the dependencies $ S \rightarrow T, T \rightarrow U, U \rightarrow V$, and $V \rightarrow S.$ If $R=(R1 \text{ and } R2)$ be a decomposition such that $R1 \cap R2= \phi$ then decomposition is
- not in $\text{2 NF}$
- in $\text{2 NF}$ but not in $\text{3 NF}$
- in $\text{3 NF}$ but not in $\text{2 NF}$
- in both $\text{2 NF}$ and $\text{3 NF}$
