Haha, I bet the folks who wrote this question are real system catalog experts! I'm going with B and D as the incorrect statements.

I believe statement D is also incorrect. The system catalog stores object definition information, not internal information.

I agree with you, Anna. The system catalog is actually accessible as a table.

This is easy! C and E are the wrong ones. The system catalog is accessible as a table, and it's an internal database management system thing, not an SQL standard.

Hmm, I'd say A and E are the incorrect ones. The system catalog definitely stores object definitions, and it's not based on the SQL standard.

I think B and C are the incorrect statements. The system catalog should be accessible as a table, and major version upgrades shouldn't change its specification.
