I believe statement C is also correct, as using the FULL option can help reduce file size.

If you're not using ANALYZE, you might as well just throw darts at the query plan and hope for the best.

B is also correct. ANALYZE doesn't lock the table, which is a nice feature.

E is just plain wrong. Even without ANALYZE, you can still see the data, it just might not be optimized.

I'm not sure about C. Isn't that more related to VACUUM than ANALYZE? Either way, A and D are definitely the right answers.

A and D seem to be the correct statements. ANALYZE updates the statistics, and if it's not used, the query optimizer may not choose the most efficient plan.
