To efficiently prevent users (except those with the Sales Manager profile) from changing the Opportunity Status to Closed Lost when the lost reason is blank:

Option D: An error condition formula on a validation rule on Opportunity

To check the code coverage of a class after running all tests, a developer can use the Developer Console.

Option B: View the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab.

In the Developer Console, navigate to the Tests tab.

After running tests, the Overall Code Coverage panel displays code coverage statistics.

You can see the coverage percentage for individual classes.

To fire an exception in Apex, the developer must use the throw statement along with an instance of the exception.

Option A: throw new ParityException();

Correct Way.

Explanation:

Creates a new instance of ParityException with no message and throws it.

Syntax is correct for throwing an exception.

Option C: throw new ParityException('parity does not match');

Correct Way.

Explanation:

Creates a new instance of ParityException with a custom message and throws it.

The exception class inherits from Exception, which allows passing a message to the constructor.

Options Not Correct:

Option B: new ParityException('parity does not match');

Incorrect.

Explanation:

This statement creates a new instance of ParityException but does not throw it.

Without the throw keyword, the exception is not fired.

Option D: new ParityException();

Incorrect.

Explanation:

Similar to Option B, this creates a new instance but does not throw it.

The exception will not affect the flow unless it is thrown.

Conclusion:

The two ways the developer can fire the exception are:

Option A: throw new ParityException();

Option C: throw new ParityException('parity does not match');

Both use the throw statement to fire the exception.
