B. Reference the jquery, jquery.validate and jquery.validate.unobtrusive script files in the view.

C. Open the web.config file at the project root, and set the values of the ClientValidationEnabled and UnobtrusiveJavaScriptEnabled keys to True.

D. For each form element, use the Validator.element() method to validate each item.

E. Add data annotations to the model properties that the view uses.

Answer: B,C,E

Explanation: B: . The validation can be implemented using jQuery and jQuery validation plug-in (jquery.validate.min.js and jquery.validate.unobtrusive.min.js).

C: When you are developing an MVC application in Visual Studio 2012 then the client-side

becomes enabled by default, but you can easily enable or disable the writing of the

following app setting code snippet in the web.config file.

</appSettings>

</configuration>

E: The jQuery validation plug-in takes advantage of the Data Annotation attributes defined in the model, which means that you need to do very little to start using it.
