Which normal form eliminates redundant data?

Question

Quizplus · Accepted Answer

Second normal form eliminates redundant data by ensuring that non-key attributes depend only on the primary key and not on any other non-key attributes. Third normal form further eliminates redundancies by ensuring that non-key attributes do not depend on other non-key attributes. First normal form deals with atomicity of the data, but does not necessarily eliminate redundancies. Therefore, option B (Second and third) is the best choice.
