You need "get the record for the Viridian City Gym and all its trainers". But A answer returns all trainers without "record for the Viridian City Gym "

A. This query fetches all Trainer__c records where the related Gym__c record has a Name field equal to "Viridian City Gym". The "__r" notation is used to traverse the relationship from the Trainer__c object to the Gym__c object. "Gym__r.Name" is used to reference the Name field on the related Gym__c object.

Sorry but, based on how the question is written, I don't agree ... 'Which SOQL query will get the record for the Viridian City Gym and all its trainers?' It is asked to retrieve the record for the Viridian City Gym AND all its trainers. With A, you only get the trainers for the Gym and not the Gym record :)
