E$\_$P$($SSN$,$ PNUMBER, HOURS, ENAME, PNAME, PLOCATION$)(2)$

The functional dependencies are:

FD$1$: $\{$SSN$,$ PNUMBER$\}->\{$HOURS$\}$

FD$2$: $\{$SSN$\}->\{$ENAME$\}$

FD$3$: $\{$PNUMBER$\}->\{$PNAME$,$ PLOCATION$\}$

$$

A$.(2$ points$)$ Is it in $3$NF $(3$rd Normal Form$)?$

B$.(2$ points$)$ If not, in what form is it $($non$-1$NF$,1$NF$,$ or $2$NF$)?$

C$.(12$ points$)$ If it is not in $3$NF$,$ then normalize it to $3$NF$.$
