Answer: Second normal Form
A relation is in second
normal form (2NF) if and only if it is in 1NF and every non-key attribute is
fully dependent on the primary key.
A relation R is in first
normal form (1NF) if and only if all underlying domains contain atomic
values only.
A relation R is in third
normal form (3NF) if and only if it is in 2NF and every non-key attribute
is non-transitively dependent on the primary key.
