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.

Account.Industry = 'Technology'];

Accounts.Industry = 'Technology'];

I'm going with option A. It's always best to use the 'r' suffix for relationship fields. Gotta love those Salesforce naming conventions!

Option D looks good to me. 'Job_Application_c' is the correct field name, not 'Job_Applications_r' or 'Job_Applications_c'.

I'm not sure about the use of 'Accounts' vs 'Account' in the options. Shouldn't it be 'Account.Industry' in all of them?

I think option A is the most efficient statement. Retrieving the Contact records and their related Job_Application__c records in a single query seems like the best approach.
