This contrasts with a materialized view, which stores the result set of the query and requires explicit refreshing to update its contents.

Option A: True - This option is incorrect. A dynamic view does not materialize its contents; instead, it executes its query or queries each time it is referenced.

Conclusion:
The statement "A dynamic view is one whose contents materialize when referenced" is Option B: False. Therefore, the correct answer is False.
