A custom object Trainer_c has a lookup field to another custom object Gym___c. Which SOQL query will get the record for the Viridian City gym and it's trainers?

This SOQL query correctly uses a parent-to-child subquery to first find the `Gym__c` record by its `Name` and then, within that query, retrieves all related child `Trainer__c` records by using the plural relationship name of the child object, which is typically 'Trainers' for a lookup from `Trainer__c` to `Gym__c`.

The subquery uses `Trainer_c` (the object's API name) instead of the plural relationship name (e.g., `Trainers`), which is required for parent-to-child SOQL queries.

This is a child-to-parent query that would return only `Trainer__c` records whose associated gym name is 'Viridian City Gym', rather than retrieving the gym record itself and its entire list of trainers.

This query uses an incorrect comparison operator '-' instead of '=' in the `WHERE` clause, making the query syntactically invalid.
