What is the recommended way to display field data from the related Review__c records in a Visualforce page for a single Position__c record?

1. Utilize the Standard Controller for Position__c and cross-object Formula Fields on the Job_Application__c object to display Review__c data.

2. Utilize the Standard Controller for Position__c and a Controller Extension to query for Review__c data.

3. Utilize the Standard Controller for Position__c and expression syntax in the Page to display related Review__c through the Job_Application__c inject.

4. Utilize the Standard Controller for Position__c and cross-object Formula Fields on the Review__c object to display Review__c data.

The correct answer is: Utilize the Standard Controller for Position__c and cross-object Formula Fields on the Review__c object to display Review__c data.

To effectively display field data from related Review__c records in a Visualforce page for a single Position__c record, utilizing the Standard Controller for Position__c along with cross-object Formula Fields on the Review__c object is a recommended approach. This method leverages the ability of formula fields to derive and display information from related objects, allowing for a more efficient and readable implementation without the need to perform additional queries or create controller extensions. Cross-object formula fields in Salesforce allow you to reference fields from parent or related records. Since Review__c records are related to Position__c (likely through a relationship such as Job_Application__c), you can create formula fields on the Review__c object to pull in necessary data from either the Position__c record or any other related records. This method helps in maintaining a clear separation of logic and presentation, as it utilizes Salesforce's built-in capabilities for automatically populating field data based on relationships, simplifying the Visualforce page's underlying controller logic. This also aligns well with Salesforce best practices, which promote the use of declarative features over programmatic solutions when possible. Using this technique results in more straightforward and maintainable code since it relies on Salesforce's data model and processing capabilities, allowing developers to
