Wait, why would we need to filter by Account Industry?

I think Option C looks familiar, but I’m not entirely confident. I remember something about using the WHERE clause effectively in these types of queries.

I have a hunch that the answer involves using a subquery to get the Job_Application__c records, but I’m a bit confused about how to structure it correctly.

I think we did a similar question in class about retrieving related records. I feel like filtering by Account Industry is key, but I can't recall the exact syntax.

Okay, I think I've got a strategy. I'll need to use a join to bring in the related Job_Application__c records, and then filter for the specific Account Industry.

Hmm, I'm a bit confused by the master-detail relationship between Contact and Job_Application__c. I'll need to think through how that impacts the query.
