THE following database schema is in 4NF. What can you infer about multi-valued dependencies?

A

C

D

A

B

C

E

E

F

A-It does not have multi-valued dependencies.

B-The multi-valued dependency A ->-> C does not hold. If the multi-valued dependency A ->-> C held, the database would not be in 4NF.

C-The multi-valued dependency A ->-> B does not hold. If the multi-valued dependency A ->-> B held, the database would not be in 4NF.

D-Neither the multi-valued dependency A ->-> C nor the multi-valued dependency A ->-> B holds. If either of those multi-valued dependencies held, the database would not be in 4NF.
