You have created an ASP.NET application that runs on your company's Web server. One of the pages contains an HTML server CheckBox control that, when checked, displays a list of products in a ListBox control. You have set the AutoPostBack property of the check box to true so that the list box will immediately fill with data when the check box is clicked. Most users report that the application runs properly, but some users report that clicking the check box does not fill the list box with products.

Which of the following scenarios would result in the list box not updating when the check box is clicked on some users' browsers?

a. ActiveX control support has been disabled on some users' browsers.

b. HTML version 4.0 or later is not supported by some users' browsers.

c. Cookies have been disabled on some users' browsers.

d. Scripting has been disabled on some users' browsers.
