A set of contacts are closed when the relay is energized. These contacts are classified as normally closed.

In relay terminology, the label normally closed means the contact is closed when the coil is not energized, and energizing the coil opens it. Conversely, contacts that close when the coil is energized are normally open. So a set of contacts that are closed only after energizing the relay fits the normally open classification, not normally closed. Therefore, the statement is false.
