Q$5.(8\%)$ Consider the relation $R(A,B,C,D,E,F,G,H,$I,$J,K).$ A is the primary key. $($B$,$ C$)$ forms a candidate key. The following functional dependencies exist among the attributes of the relation: $A\{A,B,C,D,E,F,G,H\}$;$\{B,C\}\{A,B,C,D,E,F,G,H\}$;$EF$;$C\{G,H\}$;$G\{I,J,K\}$ Transform this relation into a set of $1NF,2NF,3NF$ relations.
