Question 298

The Job_Application__c custom object has a field that is a Master-Detail relationship to the Contact
object, where the Contact object is the Master. As part of a feature implementation, a developer
needs to retrieve a list containing all Contact records where the related Account Industry is
Technology while also retrieving the contacts Job_Application__c records.
Based on the objects relationships, what is the most efficient statement to retrieve the list of
contacts?

• A. [SELECT Id, (SELECT Id FROM Job_Applications_r) FROM Contact WHERE Account.Industry = Technology];
• B. [SELECT Id, (SELECT Id FROM Job_Applications_r) FROM Contact WHERE Accounts.Industry = Technology];
• C. [SELECT Id, (SELECT Id FROM Job_Applications_c) FROM Contact WHERE Accounts.Industry = Technology];
• D. [SELECT Id, (SELECT Id FROM Job_Application_c) FROM Contact WHERE Account.Industry = Technology];
