Choice d is correct. ASP.NET applications rely on _JavaScript to call server-side events. When scripting is disabled in a browser, an ASP.NET application will be unable to call any server-side event code. Because scripting has been disabled on some users' browsers in this scenario, the code to update the list box is never called. When a control's AutoPostBack property is set to true, a form post will occur when the control's Change event is raised. Change events do not normally cause a post to occur. Scripting must be enabled in browsers for the AutoPostBack property to function.

None of the other options would have any bearing on this scenario. Because neither the check box nor the list box is an ActiveX control, the browsers' ActiveX control settings are irrelevant. HTML version 4.0 support is not required for these controls. Cookies are not required in this scenario.
