Which join $($or joins$)$ would be appropriate for this dataset when joining the "book$\_$meta$\_$data" table and the "book$\_$ratings" table given that you want to analyze only books that have ratings?

Note: Assume that the "book$\_$meta$\_$data" table is on the screen first and is on the "left" and the "book$\_$ratings" table is added second and is on the "right".
