- A. Share the Case_Defect_c record.
- B. Share the parent Case record.
- C. Share the parent Defect_c record.
- D. Share the parent Case and Defect_c records.
Answer: D
Explanation:
To share a specific Case-Defect_c record with a user, the developer should share the parent Case and Defect_c records. This is because the Case-Defect_c object is a junction object that has two master-detail relationships with the Case and Defect_c objects. A junction object inherits the sharing and security settings from its two master objects, so the user needs to have access to both of them to view the junction object record1. Sharing only one of the parent records is not sufficient, as the user will not be able to see the other related record.
Sharing only the junction object record is not possible, as it does not have its own sharing settings.

Explanation:
To check the code coverage of a class after running all tests, the developer should view the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab. This panel shows the code coverage for each class and trigger in the org, as well as the overall code coverage percentage.
The developer can also double-click on a class or trigger name to see the code coverage details, such as which lines are covered or not covered by tests.
The other options are not correct because:
* A. View the Code Coverage column in the list view on the Apex Classes page. This option only shows the code coverage percentage for each class, but not the details of which lines are covered or not covered by tests. It also does not show the code coverage for triggers or the overall code coverage percentage.
* B. View the Class Test Percentage tab on the Apex Class fist view m Salesforce Setup. This option does not exist in Salesforce Setup. There is no such tab or view for Apex classes.
* D. Select and run the class on the Apex Test Execution page in the Developer Console. This option only runs the test methods in the selected class, but does not show the code coverage for the class or other classes and triggers in the org.
