It was not worth paying for the contributor access for this exam. Most of the questions are pretty straight forward but the given answers are incorrect. And they don't even update them after getting feedback through the discussion.
It is clear that answer shown here is wrong. Why can't moderator fix this? So many question for this test has wrong answers.
The correct answer should be "stores data without a fixed schema"
Non-relational databases are designed to handle a wide variety of data types and do not impose a fixed schema on data, allowing for more flexibility and scalability.
A non-relational database stores relational data? It's D. Structured data follows a schema, semi and unstructured do not follow specific schema's. Non-relational databases store the latter and so the answer is D.
Should be B.
From: https://www.pluralsight.com/blog/software-development/relational-vs-non-relational-databases
