Find all minimal candidate keys and primary key and normalize the attributes using the following functional dependencies:

Attributes: (A,B,C,D,E)

1- FD: A->BC; BC-> DA; D->E

2- FD: A->BC; BC-> DA; D->E; B->D

3- FD: A->C; C-> D; B->E

4- FD: AB->C; C-> D; B->E

5- FD: A->B; C->DE

6- FD: A->BCDE

7- FD: A->BCDE; D->E

8- FD: A->B; B->C; C->D; D->E
