Challenge 1 / 1

What's the key reason why adding both innerJoin() and addSelect() helps reduce the number of database queries in our Symfony app?

It tells Doctrine to fetch all related data at once in a single query instead of doing individual queries for each part.

It changes the default order of retrieval, hence sorting the data more efficiently.

It allows importing data from an external database, which lowers the query count.

It removes duplicates from the results, leading to fewer queries and better performance.
