R represent Table, and (a, b, c, d) represent columns in the table.
Since all the values are atomic and we have a given primary key(a, b) we can say it is in the 1NF.
But
a, c -> b, d ( meaning b, d can be determined from a, c). Here we have partial dependency, since (b, d) is not being fully dependent on the primary key (a, b), even though the answer turn out to be incorrect.
