To answer this question, we need to understand the purpose of the EnableViewState property in ASP.NET.

The EnableViewState property determines whether the state of a control on a web page is saved and restored across postbacks. By default, EnableViewState is set to true, which means that the state of controls, including user input on a form, is saved and restored automatically.

So, the correct answer is:

A. Yes

EnableViewState allows the page to save the user's input on a form.
