We eliminate the transitive dependency to make the Relation in 3NF. So how in point #2 Transitive Dependency = 3NF?

Mam can u please elaborate.
Regarding point 1, suppose on R(A, B, C) the FD are A->B and B->C Now CK = A (only one) But it is not in 3NF because of B -> C. It is in 2NF
is point 2 correct? No Trans dep in 3 NF.
