You need to design a solution for capturing an exception.
Which approach should you recommend?

D.

Explanation:
HandleErrorAttribute
Represents an attribute that is used to handle an exception that is thrown by an action method.
The HandleErrorAttribute attribute in ASP.NET MVC lets you specify how to handle an exception that is thrown by an action method. By default, when an action method with the HandleErrorAttribute attribute throws any exception, MVC displays the Error view that is located in the ~/Views/Shared folder.
